The aim of this subject is to develop a thorough understanding of the main concepts, techniques and performance criteria used in the analysis and design of digital communication systems. Such systems lie at the heart of the information and communication technologies (ICT) that underpin modern society. Digital communications have become the preferred option for many communication devices, replacing analogue systems, due to their robustness to noise, ease of standardisation and increased scale of integration.
This subject provides an in-depth treatment of the main concepts and techniques used in the analysis and design of digital communication systems.
- Source coding; data compression; entropy;
- Digital modulation and demodulation, with and without bandwidth constraints; signal constellations in signal vector space; M-ary signalling and probability of error calculations for AWGN channels; Nyquist’s criterion, pulse shaping and equalisation; sequence detection; Viterbi’s algorithm;
- Mutual information and channel capacity; BSC and erasure channels; Shannon bounds; channel coding; erasure coding; block codes; convolutional / trellis codes; error-correction; and decoding methods.
This material is complemented by examples such as JPEG, the compact disc, satellite communication systems, and mobile communication systems.
