Module Leader: Prof. R.J. Green

Co-lecturer: Dr M.S. Leeson

Module Information

Scope

This 15 CATS module is one of the third year modules for:

Core:	Optional:
Computer and Information Engineering Electronic Engineering	Engineering

Aims

The module seeks to study the ways in which communications systems have been designed to counteract the various natural phenomena encountered in both line and radio transmission.

Learning Outcomes

By the end of the module the student should be able to...

Appreciate the main principles of electronic communication including the fact that noise and interference restrict system performance.
Determine parameters, such as error probability and signal-to-noise ratio for a system given a specification.

Syllabus

Analogue Modulation methods. Analogue broadcast radio (AM/FM/Stereo) and Television. Comparison of Analogue Systems. Random signals. Noise and Interference. Information Theory: Limits to analogue and digital communication. Introduction to digital transmission: Sampling, Pulse Modulation, TDM, Bandwidth vs Pulse Width. Coded Pulse Modulation: PCM, Delta Modulation and variants. Baseband Digital transmission: Digital signals, noise and errors, pulse shaping, ISI and eye diagrams, equalisation, pulse detection and matched filters, synchronisation. Bandpass Digital Transmission: Carrier wave modulation, Coherent and non-coherent binary systems, Comparison of digital systems. Error-control coding: Definitions, Linear Block Codes, Convolutional Codes, Viterbi decoding. Advanced Topics: may vary from year to year, could include topics from the following: Quadrature carrier systems, M-ary systems, Spread-Spectrum systems, Cryptography, Fading Multipath channels, Compression.
