    Executive SummaryThe realization of a workshop or a seasonal school have the objective to raise interest ofresearch community into the core technologies developed within EMPhAtiC project, togetherwith sharing/disseminating this know-how in Europe. To fulfill this objective, EMPhAtiC wasinvolved in the organization of one workshop and two seasonal schools during the second halfof the project.

    The ICT projects EMPhAtiC and 5GNOW have successfully jointly organized the workshopAdvanced Multi-Carrier Techniques for Next Generation Commercial and Professional MobileSystems on 26th of August 2014 during The Eleventh International Symposium on WirelessCommunication Systems - ISWCS14 in Barcelona, Spain. ISWCS is a yearly successful sym-posium on wireless communications that has been always hosted in Europe with exception ofits first edition. With an average of 300 attendees it provide an appropriate framework for theprojects workshop.

    For the joint EMPhAtiC/5GNOW workshop, an open call for papers was officially publishedin February 2014 and the deadline for submissions was 18th of April, 2014. This openedthe possibility for authors external to both projects to publish their results and allowed publicvisibility of the workshop. Also authors participating in other ICT projects had the possibilityto publish their results. The partners of both projects were also recommended to submittheir contributions. The result was the acceptance of 8 contributions from EMPhAtiC, 1 from5GNOW, 1 from METIS and 2 from other groups. The workshop had the duration of oneday starting at 9:00 and finishing at 16:20. The attendance was considered very good with theaudience fluctuating between 30 and 45 persons, especially if considering that 3 other workshopswere running in parallel.

    NEWCOM# (Network of Excellence in Wireless Communications) organizes seasonal train-ing schools and emerging topic workshops for the dissemination of the activities, education andtraining purposes. The NEWCOM# Spring School Flexible Multicarrier Waveforms for FutureCommunications Wireless Networks took place at SUPELEC, Campus of Rennes, France, from21st to 23rd of May 2014, and was organized with the collaboration of other EU foundedprojects: 5GNOW and EMPhAtiC. The school had 2 tutorials and 7 lectures, from which 1tutorial and 3 lectures were given by collaborators of EMPhAtiC partners. The school had 50attendees in total, coming from 12 different countries.

    The Jyvskyl Summer School is organized by the Faculty of Mathematics and Science andthe Faculty of Information Technology at the University of Jyvskyl, Finland. The JyvskylSummer School is one of the largest, and oldest multidisciplinary Summer Schools in Finland,and it has retained its place as an important international meeting place for young experts ofnatural sciences and information technology. Over twenty-four years the Summer School hasoffered 461 courses which have been attended by 6984 students and 880 lecturers.

    The 24th Jyvskyl Summer School took place from the 6th till 22nd of August 2014 andit offered 27 courses for advanced masters students, graduate students, and post-docs in thevarious fields of science and information technology. In the Summer School courses there were41 lecturers altogether.

    1. IntroductionPublic Safety organizations are using radio communications systems for the day to day op-erational needs (called PP1: Public Protection in day to day mode), for exceptional events(called PP2: Public Protection in exceptional planned events: sports events, cultural events,demonstrations, etc.), and for disaster recovery conditions (called DR: Disaster Relief: excep-tional unplanned events). These usages are called collectively as PPDR, which corresponds toProfessional Mobile Radio (PMR) services for Public Safety organizations.

    Today they use dedicated radio communications systems TETRA, TETRAPOL in Europeand in a large part of the word, APCO25 in North America) primarily for voice communicationsand also for low rate data transmissions. This is due to the technological limitations of currentlydeployed PMR /PPDR systems, which only use a small frequency bandwidth and have thuslimited throughput.

    In recent years Public Safety organizations in the UK, France, Netherlands and some othercountries have been conducting trials on high-speed data communications, in line with the PMRevolution trend. There is clearly a need amongst these organizations to have in 5 to 10 yearsnationwide networks to support mission critical applications like those listed above.

    Services like Imaging, Digital mapping / Geographical information services, Video (real timeand slow scan), and data base access remote require much higher data rates than what thecurrently deployed PMR/PPDR systems can support. Broadband techniques using bandwidthsin the range of 1.4, 3, or 5 MHz, such as the 3GPP LTE system, enable high data rate transmis-sions and demanding PPDR data applications. The above mentioned services and applicationsare becoming more and more important for the missions of Public Safety organizations.

    1.1 EMPhAtiC project motivation

    The EMPhAtiC project addresses the described trends and needs to upgrade the PMR/PPDRnetworks (TETRA, TETRAPOL, TETRA TEDS, APCO 25, ETSI dPMR, iDEN, and others)towards supporting broadband data communications services. The new required capacity can beachieved in two complementary ways: by obtaining new frequency bands for PPDR data servicesand by fitting a novel broadband data service within the scarcely available spectrum devoted toPMR systems. To satisfy the growing demands, both directions actually have to be followed.In EMPhAtiC project we focus on the latter approach, which can be seen as a very challengingevolution path, but also the most realistic opportunity to benefit from the advantages of latestdevelopments in multicarrier waveforms and related signal processing techniques. One of themajor issues is being able to introduce new broadband data services within the current frequencyallocation, in coexistence and cohabitation with current PMR/PPDR systems.

    1.2 Vision & Objectives

    The considered coexistence scenario, deployment of broadband data service in a band alreadyoccupied by narrowband PMR channels. In such a scenario high flexibility and spectral agility incombination with efficient fragmented spectrum use are necessary requirements for the broad-band system. To reach good spectral efficiency and minimize interferences between the differentservices, well-contained spectrum, providing improved adjacent channel protection, is critical.The general objectives of EMPhAtiC are:

    to propose an innovative technological solution allowing increased data throughputs for

    ICT-EMPhAtiC Deliverable D10.3.2 5/21

  • ICT 318362 EMPhAtiC Date: 13/2/2015

    Public Safety radio-communication systems in cohabitation with existing networks in thesame frequency bands, to facilitate a smooth migration towards broadband systems.

    to develop an efficient and highly flexible/variable filter-bank processing structure for usein heterogeneous environments with irregularly fragmented spectrum.

    enable a flexible spectrum use for mobile broadband applications, while taking into accountcommercial and regulatory opportunities and constraints.

    development and use in PMR/PPDR context of advanced multicarriers waveforms andsignal processing techniques and find applications in various other scenarios of flexiblespectrum usage and cognitive radio.

    Radio scene analysis for flexible spectrum usage is also an important technological objec-tive.

    demonstration of the superiority of the EMPhAtiC architecture when compared to priorknown solutions.

    1.3 Concentration and Audience

    The results obtained in the EMPhAtiC project will benefit all parties in the wireless arena:

    Academia and research centers first contributing with their solid backgrounds in thisfield, will benefit from EMPhAtiC to improve their research profiles. The work will stip-ulate dissemination of this knowledge to undergraduate and PhD students. This willgenerate skilled engineers, which will be well prepared to start their professional career inthe wireless sector.

    Industrial partners The benefits of the Project for Industrial Partners will be felt in theareas of improved products and solutions available through the Project. This will allowthe parties to take advantage of improved system performance due to new ideas beforetheir competition. Therefore, the target (from industrial point of view) is to improve thepositioning of European industry in the PMR domain in terms of research, technologymastery and evolution for the future. Two major worldwide companies, CASSIDIAN andTCS, are major actors in the EMPhAtiC projects and they are strong and prime playersin the domain of PMR. Dynamic SMEs working in the domain of broadband mobileradio communications are also involved in the development of the European industrialpotential in the PMR/PPDR domain and to support European industry positioning onmobile wireless broadband systems.

    Users who will eventually be offered optimized services because of the higher flexibilityand efficiency resulting from advanced wireless systems providing high quality of services.

    Society The European Industry has been in the forefront of wireless technologies forexample with the early introduction and standardization in the nineties of the DigitalMobile Solution of GSM. The early adoption of new technologies has proven an enormoussuccess for the involved industries first and lastly for the society they are serving. Thesociety can take advantage in advance of other competing countries of an improved serviceand a technological prestige that finally rubs on other aspects of the economical toil.

    The focus of EMPhAtiC is to improve efficiency of mobile broadband networks especiallyin term of radio coverage and capacity. This target is the keystone for reducing thecost of deployment of radio networks for PMR applications, and also more generally forBroadband Mobile Radio networks. This enables major cost savings in radio networkdeployment, especially in suburban and rural areas, by minimizing the number of radiosites required. This lowers also the cost of communications onto mobile radio networksby using more efficiently the scarce resource of radio frequencies.

    2. Workshop at the International Symposium on Wireless

    Communication Systems - ISWCS 2014

    The International Symposium on Wireless Communication Systems is yearly event and in 2014was on its eleventh edition. The symposium started in 2004 and, with exception of its firstedition, it always took place in European countries. As a consequence, a great number ofcontributions and participants come from European universities, research centers and industries.The average number of participants is around 300 per year.

    2.1 The eleventh ISWCS

    The symposium was organized by the Centre Technologic de Telecomunicacions de Catalunya(CTTC) between 26th-29th August 2014 and the venue was the conference center of the HotelSB ICARIA Barcelona, Spain.

    Besides the joint EMPhAtiC/5GNOW workshop, three other workshops took place on thefirst day. On the following three days there were 6 plenary talks by keynote speakers, 5 tutorialsand 31 technical sessions (25 regular and 6 special sessions). The open call counted 397 papersubmissions and from them 191 were accepted, resulting in 49% acceptance rate.

    According to the call for papers, ISWCS14 had the following overview:

    The aim of this symposium is to provide a forum for researchers and technologists topresent new ideas and contributions in the form of technical papers, panel discussions as well asreal-world evaluation of many ideas in wireless communications, networking and signal process-ing employed to support the needs of the Information Society. This eleventh symposium willbring together various wireless communication systems developers to discuss the current sta-tus, technical challenges, standards, fundamental issues, and future services and applications.ISWCS14 seeks to address and capture highly-innovative and state-of-the-art research fromacademia, the wireless industry as well as standardization advances. The scope of the con-ference includes a wide range of technical challenges encompassing wireless communications,information theory, quality of service support, networking, signal processing, cross-layer designfor improved performance, and future wireless broadband systems.

    The symposium was divided into three tracks:

    Track 1: Communication theory, signal processing, information theory, antennas andpropagation

    Track 2: Networking, protocols, cognitive radio, wireless sensor networks, services andapplications

    Track 3: Special sessions

    There was a best paper award for each of the tracks.

    The symposium technical sponsors were the Institute of Electrical and Electronics Engineers(IEEE), IEEE Vehicular Technology Society, the IEEE Communication Society, and the Euro-pean Association for Signal Processing (EURASIP). In addition, ISWCS14 had the financialsponsorship from the CTTC.

    2.2 Workshop: Advanced Multi-Carrier Techniques for Next Genera-

    tion Commercial and Professional Mobile Systems

    For the joint EMPhAtiC/5GNOW workshop, a call for papers was officially published in February2014 and the deadline for submissions was 18th April, 2014. This opened the possibility forauthors external to both projects to publish their results and allowed public visibility of theworkshop. The project partners were strongly recommended to submit their contributions too.The result was the acceptance of 8 contributions from EMPhAtiC, 1 from 5GNOW, 1 fromMETIS and 2 from other groups.

    The workshop had the duration of one day starting at 9:00 and finishing at 16:20. The atten-dance was considered very good with the audience fluctuating between 30 and 45 participants,especially if considering that 3 other workshops were running in parallel.

    In the following sections more details about the joint EMPhAtiC/5GNOW workshop arepresented. We will start here with the call for papers of the workshop, then the final workshopprogram is shown and a few pictures of the event give some impressions of its success.

    2.3 Call for papers

    Future communication systems will be characterized by their needs for increased flexibility,high data rate, efficient use of the fragmented spectrum, and bandwidth-efficient handling ofunsynchronized transmissions. Heterogeneous networks, with co-existent systems of differentbandwidth characteristics,in cell-based, device-to-device, and ad-hoc networking configurationsshould be accommodated. Such scenarios include cognitive radio and the co-habitation ofbroadband data services with narrowband professional mobile radio (PMR). Furthermore, go-ing beyond the Long Term Evolution (LTE) standard is a current trend, stemming from theneed to improve the spectral characteristics and maximize the spectral efficiency, while preserv-ing/improving the offered quality of service.

    Orthogonal frequency division multiplexing (OFDM) has been established as a simple andpowerful approach to cope with many of these issues. However, CP-OFDM is not the most ap-propriate solution in the above scenarios. Nearly orthogonal, asynchronous waveform approachessuch as filter bank multicarrier (FB-MC) techniques or even non-orthogonal waveforms, such asgeneralized frequency division multiplexing (GFDM) and universal filtered multicarrier (UFMC)have recently been shown to significantly outperform CP-OFDM in relevant application sce-narios. The use of spectrally well-contained subcarrier frequency responses provides a majorimprovement in spectrum efficiency and relaxes the synchronization requirements and limita-tions for system cohabitation.The gains come, however, at the costs of increased complexity.

    This workshop aims to gather researchers, engineers and practitioners both from academiaand industry, with the aim to inspire the development of new solutions for flexible waveforms.The workshop is supported by the European ICT projects EMPhAtiC and 5GNOW. I twillwelcome contributions presenting advances on related topics including but not limited to thefollowing:

    3. Lectures at the NEWCOM# Spring School

    3.1 NEWCOM#

    NEWCOM# (Network of Excellence in Wireless Communications) is a project funded underthe umbrella of the 7th Framework Program of the European Commission (FP7-ICT-318306).NEWCOM# pursues long-term, interdisciplinary research on the most advanced aspects ofwireless communications like Finding the Ultimate Limits of Communication Networks, Oppor-tunistic and Cooperative Communications, or Energy- and Bandwidth-Efficient Communicationsand Networking.

    In one of its tracks, namely Track 3: training, dissemination and human capital, NEWCOM#organizes seasonal training schools and emerging topic workshops for the dissemination of theactivities, education and training purposes. Seasonal schools are dedicated to fundamentaltopics of specific relevance to the joint research pursued in Track 1: Theoretical research issuesof NEWCOM# and typically last for several days. The seasonal schools consist of lectures onbasic and state-of-the-art methods, taught by experts from within and outside NEWCOM#.PhD students can thus benefit from the integrated expertise of the NEWCOM# consortiumthat adds to the guidance provided by the direct PhD supervisor. The courses are sometimescomplemented with student discussion (or poster) sessions that are organized to foster theexchange of scientific ideas and improve the networking of PhD students.

    3.2 Spring School: Flexible Multicarrier Waveforms for Future Com-

    munications Wireless Networks

    The NEWCOM# Spring School Flexible Multicarrier Waveforms for Future CommunicationsWireless Networks took place at SUPELEC, Campus of Rennes, France, from 21st to 23rd ofMay 2014, and was organized with the collaboration of other EU founded projects: 5GNOWand EMPhAtiC.

    According to the organizers, the summer school had the following objective:The goal of that event is to discuss and investigate recent achievements in the very im-

    portant and vivid research area devoted for future multicarrier systems. Currently, OFDM playsa role of the leader in practical realizations of multicarrier signaling, however it suffers fromvarious limitations, raised by the researchers and manufacturers for many years. Filter BankMulticarrier based solutions tend to become the successor of OFDM in the context of futurewireless and even wired communications systems. During the three days long event all partic-ipants will be acquainted with the arcane of the new modulations formats, covering not onlythe theoretical analysis and discussion, but also the debate on the hardware implementationissues.

    The school had 50 attendees in total, coming from 12 different countries.

    4. Lecture at the 24th Jyvskyl Summer School

    The Jyvskyl Summer School is organized by the Faculty of Mathematics and Science and theFaculty of Information Technology at the University of Jyvskyl, Finland. The Summer Schoolannually offers courses for advanced masters students, graduate students, and post-docs in thevarious fields of science and information technology. Finnish and international students fromthese fields are encouraged to take advantage of the high-quality interdisciplinary teaching ofthe School. The language of instruction is English in all Summer School courses.

    The most important aims of the Summer School are to develop post-graduates scientificreadiness and to offer students the possibility to study in a modern, scientific environment andto create connections to the international science community. The aim is to increase studentsmotivation and determination in carrying out studies and research on both theoretical andpractical level. In addition, the Summer School strives to encourage students to absorb newand innovative ways of thinking. The Summer School has been very successful in reachingthese goals.

    The Jyvskyl Summer School is one of the largest, and oldest multidisciplinary SummerSchools in Finland, and it has retained its place as an important international meeting placefor young experts of natural sciences and information technology. Over twenty-four years theSummer School has offered 461 courses which have been attended by 6984 students and 880lecturers.

    4.1 The 24th Jyvskyl Summer School

    The 24th Jyvskyl Summer School (JSS24) took place from the 6th till 22nd of August 2014and it offered 27 courses for advanced masters students, graduate students, and post-docs inthe various fields of science and information technology. In the Summer School courses therewere 41 lecturers altogether, of which 34 were from outside of the University of Jyvskyl.345 applications from students outside of the University of Jyvskyl were received, and 214from students of University of Jyvskyl. The total number of applicants reached 559 with 379students attending the School. Summer school students outside of the University of Jyvskylrepresented 44 different nationalities, and came from 30 different countries.

    A total of 27 courses were organized in the JSS24. The length of the courses varied fromthree days to ten days. In addition to lectures, most courses included exercises, demonstrations,laboratory works, or group work. The teaching in the courses was provided by 34 invited externallecturers, and 7 lecturers from University of Jyvskyl. The invited lecturers came from twelvedifferent countries, including Canada, Japan, United States, and several European countries.

    The call for Summer School was announced via the Summer School website, a network ofpartners in universities, and scientific institutions around the world, as well as the students ofthe University of Jyvskyl. Students of the University of Jyvskyl applied for each coursevia the universitys course management system (Korppi). External students applied using anelectronic application form that was available on the Summer School website. The applicationperiod was 1st of February to 30th of April 2014. The course coordinators of the SummerSchool selected students for the courses by 16th of May 2014.

    4.2 Lecture: Beyond OFDM Radio Interfaces Facilitating Spectrum

    Coexistence and Secondary Access

    The course was held from 6th to 8th of August 2014 and contained 20 lecture hours. Thelecturers were Prof. C. Faouzi Bader (SUPELEC, France) and Dr. Dmitry Petrov (Universityof Jyvskyl and MAGISTER, an EMPhAtiC partner).

    4.3 Abstract

    This course aims at delivering to the audience the in-depth analysis of various multicarriermodulations techniques, which can be considered for application in the future, flexible com-munications systems. Currently due to its great features Orthogonal Frequency Division Mul-tiplexing (OFDM) technique has been already applied in various existing wireless and wiredcommunication systems, such as DVB-T/T2/H, IEEE 802.11, IEEE 802.16, LTE, xDSL etc.Advanced future radio interface platforms with dynamic spectrum access (DSA) and sharingare considered to be the key technologies in making the best solution of the conflict betweenthe inefficient usage of the frequency spectrum and the continuous evolution in the wirelesscommunication.

    There is no doubt that multicarrier communication systems are considered as the most ap-propriate candidate for spectrum coexistence and secondary access for future cognitive systemsdue to its flexibility in allocating different resources among different users as well as its ability tofill the spectrum holes left by the primary users (PUs). However, the use of a multicarrier schemewith specific carrier shapes or another one will affect differently the overall performance of thecommunication system. Fortunately, investigations performed in many research centers andindustries within the framework of European research projects such as PHYDYAS, URANUS,and EMPhAtiC have shown that these constraints can be alleviated e.g. by application of theso-called filter-bank based multicarrier signals. One of the main features of such approach isthe great possibility for adaptation of various signal parameters (e.g. pulse shape, low out-of-band emission modulation techniques, spectrally adaptive and flexible modulation techniques,filtering techniques, etc.) which makes this solution suitable for application in future flexibleradio communication systems.

    Therefore, the plan for the course is based on two parts. First part rises a simple butnot minor question; Is OFDM the best scheme for spectrum sharing and system coexistencecontext? To answer such a question, the authors will first focus on basic theoretical aspectscentering on the following: 1) basics aspects of OFDM system will be presented followed bythe summary of the features of other multicarrier solutions (DMT, FMT, Lattice-OFDM etc.),2) next, the main features of the of filter-bank based transmission (FB-MC) systems will bepresented where aspects related to achieved capacity under different interference constraintsand total budgets in comparison with achieved by OFDM. Second part of this course focuseson the use of advanced multicarrier wave forms for spectrum sharing and system coexistencehaving as a goal applications on: TV white space, Machine to Machine, future broadbandProfessional Mobile Radio(PMR)/(PPDR) systems, and beyond LTE.
