431-327 Communication Systems

431-221 Fundamentals of Signals and Systems, and 431-325 Stochastic Signals and Systems or 620-201 Probability.

On completion of this subject students should have a good understanding of the use of signals and systems and random process theory in the modelling and analysis of communication channels.

Topics include revision of signals and systems; linear time-invariant channel models; AM and FM modulation techniques; phase-locked loop; revision of random processes and noise; noise analysis of AM and FM; transmission losses; Nyquist sampling theorem; sampling of random processes; quantisation; waveform coding; binary signalling over AWGN channel; matched filter; bit error rate calculation; examples of ISI.

All concepts illustrated by examples from wireline, wireless and optical communications.
