Radio Reception in FM Range

FM waves travel in straight lines. They are not reflected by the layers of the earth’s atmosphere and therefore do not follow the curve of the earth.

The best reception is when the broadcasting antenna can “see” the car antenna. The FM signals, which are sent by the transmitter with horizontal or vertical polarization (depending on country), can be received best with an antenna that is mounted in a position that is open to sides (the signals “see” the full length of the antenna).

A disadvantage of FM is that its range is lower than AM signals.

If the vehicle is out of the range of the transmitter tower (the sound quality becomes poor and there is noise or interference), a different frequency should be selected.

Basics

FM waves are reflected by building, hills etc. This results in reception from several directions (multipath).

This can cause the direct signal to be deflected even in built-up areas or mountains. This reflection could cause poor quality reception.

In some cases, the radio tuner picks up both the direct and also a reflected signal from the transmitter. This overlapping of the direct and reflected (delayed) signals can cause reception interference in the form of sound distortion in the speaker. Furthermore the time difference between the direct and indirect signal causes the reception quality to vary depending on the vehicle position.

FM waves cannot pass through hills, buildings and similar obstacles without being impaired. If the vehicle enters such an area, only poor or no reception is possible. This occurs when you drive through mountains or between high-rise buildings. The range depends on the transmission power and the height of the transmitter antenna from the ground. Transmitter antennas are normally placed on towers, tall buildings or mountains.

Antenna Properties

Reception Properties of a Standard FM Antenna

The blue area indicates the direction-related reception sensitivity of the antenna. Here you can see that the antenna is sensitive to signals from all directions.

Highcut

One way to reduce the interference is the “highcut method”. The disadvantage of this method is that “cutting” the high frequencies has a negative effect on the sound in this range (volume fluctuation high cut).

The audio amplifier in the car radio amplifies all frequencies that can be heard by the human ear to a level appropriate to the human sensory range.

Technical Suppression of Multipath Interference

As multipath interference is unpleasant particularly in the higher audible frequency range, a technical solution to reduce interference is needed.

Basics

If interference occurs in the upper frequency range due to multipath reception, it is suppressed by the highcut function in the FM tuner of the car radio.

Phase Diversity

A better method of reducing interference is the phase diversity antenna principle. This reception type basically works in the same way as a directional antenna. During operation, these antennas are continuously “turned” virtually in the direction of the signal source.

Turning the antenna is simulated by digital signal processing. The antenna is not actually rotated. However, the effect is exactly the same. The aim is to provide the direct signal with as much antenna surface as possible, and the reflected signal with as little as possible.

The phase diversity is more technically complex than highcut, since it uses two tuners and two antennas.

Signals from both antennas are digitized in an frequency analog/digital converter and processed using an adaptive algorithm. This process removes the interference signals by forming a new, directed antenna signal. The antenna power is also improved by up to 3 dB.

Distance (ft)

Diversity Antenna

Another method of reducing interference is the Field Strength Diversity Antenna system, known as Diversity Antenna. This system is based on the fact that small changes in location can have great influence on FM reception. This is particularly noticeable when a car is stopped at a traffic light and moving the vehicle a few inches changes the radio reception.

The vehicle shown in the diagram is equipped with two antennas at a distance of approximately 3 ft. The antenna in the front of the vehicle has a very high receiving level, and the rear one is very low, although the distance between the two antennas is relatively small.

The Diversity Antenna system uses two antennas, mounted in different locations on the vehicle. The double-tuner radio unit automatically selects the one with better FM signal. This process is unnoticeable for the driver.

A variation of this system uses four antennas, and the Antenna Selection Control Module J515. This module selects the two strongest signals out of the four antennas, and the double-tuner radio unit selects the one with better signal.

Audio CD (Audio Compact Disk)

Audio CDs are optical mass storage media for the digital storage of music.

The analog music signal is converted to a digital signal by an analog/digital converter.

To obtain a suitable signal from the digital signals for playback via the speakers, an analog signal needs to be formed again in the CD player using a digital/analog converter.

Analog/Digital Converter

Digital Signal

The aim of digitalization is to emulate the analog signal digitally and without interference in as small steps as possible. The higher the resolution (e.g. 8 -16 - 32 - 64 bit) of the analog/digital converter, the more authentic the sound result (emulation of the analog signal).

Basics

The CD mainly consists of a transparent carrier material (substrate), which is molded by compression injection. The top side of this carrier contains the digital information in the form of microscopic pits and lands that are arranged in a single long, spiral track (around 3.1 miles or 5 km in length).

This surface containing information is covered with a thin aluminium film and sprayed with an acrylic layer. A label can then be applied or printed on it. The information is scanned by a laser through the carrier layer without contacting it and therefore remains free of wear.

Handling and Care Information for CDs and CD-ROMs

Touch a CD only by its sides.

Avoid getting finger prints on the CD.

If a CD is dirty, never wipe the CD with circular motions. Instead wipe from the inside to the outside with a soft lint-free cloth.

Handle CDs carefully from both the underside and from the top. Do not write on the CD and do not affix labels. Adhesive labels can detach from the CD surface and jam the CD player mechanism.

All CDs should be handled carefully and always be stored in a protective case. Also keep CDs away from heat and direct sunlight.

Moving Picture Experts Group (MPEG) MP3

MP3 is a file format for audio compression. Like other formats, MP3 is based on the fact that human perception is limited. The number of sounds that people can perceive is reduced because of frequency or volume of the sound.

As this process involves losses, the original output signal cannot be reproduced completely.

The losses depend greatly on the data rate. At around 128 kBit/s, the differences from the original output are hardly noticeable in music with a low dynamic range (pop music, synthesizer, techno).

For example, with guitar and violin music, you may notice annoying differences to the original at 128 kBit/s. Average data rates of 192 kBit/s or higher are recommended for this type of music.

Non-audible frequencies, the range perceivable by adults is from 20 Hz to 18 kHz, are cut off in the frequency data.

Satellite Digital Audio Radio Service (SDARS)

Satellite radio services in the United States started in 1992 when the U.S. Federal Communications Commission (FCC) allocated a spectrum in the “S” band (2.3 GHz) for nationwide broadcasting of Satellite-based Digital Audio Radio Service (SDARS).

A Satellite Radio is a digital radio unit that receives signals broadcast by commercial communications satellite which covers a much wider geographical range than land-based radio signals.

A central digital radio transmitter sends signals to commercial satellites that orbit the Earth. Digital radio signals are then transmitted to the in-vehicle satellite radio units. A number of land-based repeaters are located throughout the US, mostly in major cities, to avoid signal obstruction by buildings and tunnels.

A in-vehicle satellite radio unit is composed by a specially designed antenna and a satellite receiver unit connected to the radio head unit.

Each receiver has an Electronic Serial Number (ESN)-Radio ID to identify it. When a unit is activated with a subscription, an authorization code is sent in the digital stream notifying the receiver to allow access to the otherwise blocked channels. A monthly fee is charged for the services.

Two companies dominate satellite radio: XM Satellite Radio and Sirius Satellite Radio. Volkswagen vehicles MY 2005 and 2006 have the option of either Sirius or XM satellite receiver. For vehicles Model Year 2007 and beyond, only Sirius receivers are available.

Sound Systems

8-Channel Amplifier (Monsoon)

The use of external multi-channel amplifier improves the sound quality inside the car in several ways:

Improved sound dynamics

Car-specific sound configuration

Greater frequency ranges

Better sound distribution

Authentic sound (concert hall quality)

An amplifier system consists of the amplifier along with the treble, mid-range and bass speakers.

The external amplifier generates the signal with the corresponding frequency response for the individual speaker outputs and uses 8-channel technology.

It has eight internal output stages that control ten speakers via ten outputs. The outputs for the rear bass and treble speakers are combined via an internal frequency filter.

The signal inputs on the amplifier are controlled via the speaker outputs on the radio unit or radio navigation unit. The radio/RNS unit must be coded to “Sound” so that the level of its output channels is reduced by 14 dB.

Self-diagnosis is performed via the CAN data bus.

The 8-channel amplifier is available in combination with radio systems Premium 5.5 and Premium 6.

10-Channel Amplifier (Dynaudio)

The 10-channel amplifier uses digital signal processing and supplies the connected speakers with an output power of 600 Watts.

A special switched-mode power supply in the amplifier ensures that even the top pulse overshoots are not cut off and therefore no signals for the audible frequencies are filtered.

The signal inputs on the amplifier are controlled via the speaker outputs on the radio unit or radio-navigation unit and digitally via the CAN data bus.

Self-diagnosis is carried out via the CAN data bus.

The 10-channel amplifier is available in combination with Premium 7 Highline and Premium 7 RNS.

12-Channel Amplifier

The 12-channel amplifier is used in the Volkswagen Phaeton and Volkswagen Touareg. It has a total of 12 outputs, to which four bass, four mid-range, two mid-range and treble and two treble speakers are connected in the Phaeton.

In the Touareg, the system is connected to four bass, four mid-range, one mid-range and treble and two treble speakers. One channel is therefore free in the Touareg.

The 12-channel digital amplifier is controlled In the Phaeton via the front information display and operating unit control unit and the CAN data bus.

In the Touareg, the 12-channel digital amplifier is controlled digitally with the radio or CD-based navigation unit via the CAN data bus.

Self-diagnosis is carried out via the CAN data bus.

Sound Systems

Digital Signal Processing (DSP)

DSP technology means that the sound curves can be programmed individually in the amplifier for each speaker output. There are special characteristic curves for each type of vehicle because the signal from each audio channel is processed individually. The goal of vehicle-specific sound configuration is to generate as authentic a sound as possible on a virtual stage in front of the occupants.

Filter Stages

The sound is processed in the filter stages. The signal amplitudes are reduced or amplified in certain frequency ranges in up to five downstream filter stages.

Time-Delay Element

The signals for the rear speakers are delayed by several milliseconds so that concert hall characteristics are created inside the vehicle.

Amplifier

Dynamic Distortion Limiter

Distortion can occur in the sound processing. This is reduced in the distortion limiter, which also keeps the harmonic distortion low.

Amplifier Stage

The processed signal is amplified in the amplifier stage and sent to the speakers.

Sound Curve

The sound curve is specially configured for the vehicle interior and stored in a characteristic curve in the amplifier. In this way, some specific frequencies that may resonate interior components are reduced. Other frequencies, which could be weakened by sound absorbing components, are increased.

Amplification dB

The actual sound curve (blue) depends on the interior characteristics. It is raised in the bass area and is thus configured for the human ear.

The sound delay of the rear speakers is maintained by the time-delay element regardless of the fader setting.

Speakers

Due to the different locations of the speakers and the different materials inside a vehicle, such as soft seats and hard windows, configuring an ideal sound is very complex.

The careful positioning of speakers allows well-balanced sound distribution in the whole interior.

AM

Amplitude modulation, technique used in electronic communication to transmit information wirelessly. In amplitude modulation, the amplitude of the RF signal is modulated with the audio signal.

Amplitude

The maximum extent of a sinusoidal wave.

Bass Speaker

Speakers for reproducing low frequencies (approximately 40 to 600 Hz).

Comfort Coding

If the radio unit was removed or the car battery disconnected, the anti-theft code does not need to be entered manually. The code number was stored in the instrument cluster the first time it was entered in the car.

However, if the vehicle and radio code numbers do not match, for example, because the radio has been installed in another vehicle, the safety code must be entered manually.

Cutoff Frequency

Frequency at which a filter starts acting. Generally the frequency at which the output signal of a circuit falls 3 dB below the original value.

Domed Treble Speaker

A dome shaped speaker.

FM

Frequency modulation, technique used in electronic communication to transmit information wirelessly. In frequency modulation, the frequency of the carrier wave varies in step with the audio signal. The amplitude remains constant.

Frequency

The rate of signal oscillations per second.

Frequency Crossover

Also called a diplexer, splits the working ranges of the frequency band between the bass, midrange and treble speakers.

GPS

Global Positioning System, a satellite system set up by the US Department of Defense that allows for determining the vehicle location.

Hertz

Measurement unit for frequency. One Hz corresponds to one oscillation per second.

74

Glossary

Mid-Range Speaker

Speakers for reproducing mid-range frequencies (approximately 600 to 4,000 Hz).

Oscillation

Period signal variations between a minimum and a maximum values.

RDS, Radio Data System

A system that transmits information in an inaudible “data telegram” in addition to the FM radio program.

Redundant

In electronics, a redundant signal is a signal that is doubled for security reasons.

Rejector Circuit

A circuit in a vehicle that blocks DC current and certain low frequencies, isolating the rear window heating wires from the rest of the electrical system. Eliminates the risk of short-circuiting the antenna system.

Sinusoidal Wave

The most simple wave. A pure sound is made of a sinusoidal accoustic wave.

Transport Mode

Vehicles leave the factory with transport mode activated. This mode switches off various electrical consumers to minimize power consumption during transportation. Depending on the vehicle type, it can only be activated up to a certain mileage. Use the instructions from the ELSA to activate or deactivate the transport mode.

Treble Speaker

Speakers for reproducing high frequencies (approximately 4,000 to 20,000 Hz).
