| EE51 ANALOGUE AND DATA COMMUNICATION | (Dr. G. Allen, Mr. J. D. Martin, Mr. V. Petrovic) |
(40 hours)
Physical sources of noise: man-made noise; natural forms of noise, sky noise, circuit noise.
Statistical properties of noise
Evaluation of noise: signal-to-noise ratio, nose figure, noise temperature.
Demodulation of analogue signals accompanied by noise: coherent and non-coherent demodulation of full carrier AM signals; demodulation of suppressed carrier AM signals; demodulation of SSB signals, demodulation of FM and PM signals; threshold levels, AM threshold, FM threshold; comparison of analogue modulation systems.
Elements of digital data communications system: review of channel capacity and information measure; typical channel characteristics, noise and distortion, equalisation; timing information, synchronous and start stop systems.
Baseband data transmission: error performance, digital waveforms, signal shaping; shaping the transmitted spectrum, bipolar and high density codes.
Modems: performance and comparison of different styles of modulation under realistic operating conditions; multi-level systems; synchronisation.
Data transmission: layered nature of data communication; general requirements.
Formatted data: bit and frame synchronisation; character formats, calculation of error performance; block protocols for ARQ operations.
Data coding: principles of linear shift register circuits; scramblers, encryption, data security codes; error control coding, block and convolutinal [sic] codes, fec codes, burst errors and independent errors.
Data networks: general principles of multiplexing and concentration; examples of typical network structures, packet switching, local networks, telecontrol.
