1-1 GSM System
1-1-1 Calls
GSM¨ is an acronym for Global System for Mobile communications©, using TDMA for wide-area cellular operation. The GSM system consists of the sub-systems shown;The Mobile Station (MS) talks to the Base Station System (BSS) via an RF air interface. The Base Station System(BSS) consists of Base Transceiver Station (BTS) and a Base Station Controller (BSC). The microwave linkbetween BTS and BSC is called an Abis interface. Generally one BSC controls 20 to 30 BTSs, and a MobileSwitching Center (MSC) controlling the traffic among different cells would be reported back from a number ofBSSs. A Visitor Location Register (VLR) will be allocated to one MSC to find the mobiles out of their home cellby listing them to VLR. The MSC would also be connected to the Home Location Register (HLR), theAuthentication Center (AC) and the Equipment Identity Register (EIR) So the system verify that the users andequipment are legal subscriber.
1-1-2 Channels
Channels used in the GSM system can be divided into two classes - Logical and Physical channel. Physicalchannels can be described in terms of their frequency and time domain characteristics. They are the actualfrequencies and timeslots the MS and BS transmits or receives on. The logical channels are mapped onto thesephysical channels logically. Any particular and instant, physical channels may be control or traffic channels,which determines the function of a physical channel at a particular point in time.

General Description
1-1-5 Logical Channel
TCH (Traffic CH) is used mainly for transferring the speech information, and the BCH (Broadcast CH) isrelated to control information.The major function of BCH is transferring information on the downlink for MSsynchronization, identification, paging, and controll. BCH is always radiated from every cells and the MS triesto find the BCH which has highest level soon after turned on. The organization of BCH is shown belows;FCCH (Frequency Correction Channel), SCH (Synchronization Channel), and BCCH (Broadcast ControlChannel). CCCH (Common Control Channel) will play a role like a message board, and is divided into twocontrol channels - PCH (Paging Channel) and AGCH (Access Grant Channel). SACCH (Slow AssociatedControl Channel) exists every 12 frames, controlling and controls the TX power level and timing advance ofMS, transferring cell information to MS on downlink, transferring the information about RX level, Quality, andRX level of adjacent cell on uplink. FACCH (Fast Associated Control Channel) steals and changes the TCHwhen needing a Handover. SDCCH (Stand-alone Dedicated Control Channel) and RACH (Random AccessChannel) operate during the call setup procedure.

2-1 RF Part
2-1-1 Frequency Generator
The 13MHz reference clock (VCTCXO) drives the logic and RF part. The 13 MHz reference is controlled by thelogic (10bits DAC minimum) and is kept to a frequency error less than ±0.1 ppm after synchronization with theGSM network. A 540 MHz oscillator is divided by 2 to generate a fixed 270 MHz VHF LO used in the TX I,Q modulator andmixed by 270 MHz. The UHF LO for the first RX down conversion and the TX offset mixing works insuperheterodyne mode to reduce the relative bandwidth and to be able to work at a frequency greater than 1GHz.
2-1-2 Transmitter
The baseband GSM chipset (Kernel5) generates I and Q baseband signals for the transmit vector modulator.The modulator provides more than 40dBc of carrier and unwanted side-band rejection and produces GMSKmodulated signal, the ÔreferenceÕ signal at 270 MHz which passes to the offset phase-locked loop block (OPLL).The OPLL consists of a down-converter, phase detector, loop filter and transmit VCO operating at the final RFoutput frequency. The down converter mixes the UHF LO (eg. 1172 MHz) with the transmit VCO signal togenerate a ÔfeedbackÕ signal at 270 MHz. The ÔfeedbackÕ signal passes via a limiter to one port of the phasedetector. The GMSK ÔreferenceÕ signal from the vector modulator passes via a second limiter to the other inputport of the phase detector. The phase detector generates an error current proportional to the phase differencebetween the ÔfeedbackÕ signal from the down-converter and the ÔreferenceÕ signal from the vector modulator.This error current is filtered by a second order low-pass filter to generate an output voltage which depends onthe GMSK modulation and the desired channel frequency. This voltage controls the transmit VCO such that theVCO output signal, centered on the correct RF channel, is frequency modulated with the original GMSK data.The centre frequency of the transmit VCO is offset from the UHF LO frequency by 270 MHz. The OPLL acts asa tracking narrowband band pass filter tuned to the desired channel frequency. This reduces the widebandnoise floor of the modulation and up-conversion process and provides significant filtering of spuriousproducts. The OPLL architecture results in a low-noise GMSK modulated signal at 902 MHz with very lowspurious content.The RF GMSK output from the transmit VCO is fed via TX SAW filter to the RF power amplifier. The peakoutput power and the profile of the transmitted burst are controlled by means of a closed feedback loop. TheRF output from the PA is sampled with a directional coupler. The sampled signal passes to an RF detectordiode whose output voltage is dependent on the incident RF level. This ÔfeedbackÕ voltage passes to theinverting input of the loop integrator. A ÔreferenceÕ signal is generated within the baseband section undercontrol of the layer 1 software. The loop maintains zero difference between the ÔfeedbackÕ signal and theÔreferenceÕ signal. In this way, the amplitude and shape of the transmitted RF burst may be controlled by thebaseband processor. In particular, the rise and fall profiles can be controlled to meet the stringent power/timetemplates and switching transient requirements of GSM 05.05.The RF output passes to the antenna connector via an integrated TX/RX switch and lowpass filter to attenuatethe harmonics generated by the power amplifier.

2-1-3 Receiver
The incoming RF signal passes through the integrated lowpass filter and TX/RX switch. This is followed by a947 MHz SAW Band Pass Filter and a bipolar low-noise amplifier (LNA). The HD155101BF includes an activebias circuit which stabilizes the DC operating point of the LNA. The RF signal passes via a second RF SAWfilter to the first receive mixer. This mixer is implemented as a Gilbert cell within the HD155101BF. Theincoming signal at 947 MHz mixes with the UHF LO at 1172 MHz to generate a 225 MHz IF signal. The IFsignal passes from the mixer output via a 225 MHz IF SAW filter to the first IF amplifier. A further internalGilbert cell mixes the 225 MHz IF signal down to the 45 MHz second IF. The 45 MHz output from the secondmixer is filtered and passes to the AGC amplifier. The gain of the AGC amplifier is set by a DC control voltagesupplied by the baseband. The usable control range is in excess of 80dB. Finally, the AGC output signal at 45MHz passes to the demodulator and is mixed down to DC to generate I and Q baseband signals. The basebandsignals pass via baseband filter to the baseband A/D converters. The remainder of the channel filtering isperformed by the baseband chipset.

3-2-1 Power
3-2-2 Power Ramping Time Level
The power-time template requirements for mobilestations also apply to base stations. The onlydifference is that, in the base station case, no shortburst (random access) exists. To measure thetemplate, the base station has to be operated in itsbursting mode. This test cannot be performed on thebase channel, since a base station has to transmitcontinuously in all time slots. In most cases, anadditional channel besides the base channel has tobe activated or the transmitter under test is notconsidered to be configured as a base channeltransmitter. The average peak power from theprevious part of the test is used as a reference. Thetime reference is provided by the training sequencein the middle of the burst. The template has to meetthe requirements of Fig. 6. Again, the noise level of -70 dBc is dependent on the actual transmittedpower level. If this level is below -36 dBm, theabsolute level applies. The template is usuallyevaluated along with the peak power level.
