Course Leader

Prof S Godsill

Lecturer

Dr A Guillen i Fabregas

Timing and Structure

7 lectures: 1 in week 5, 2 per week in weeks 6-8

Aims

The aims of the course are to:

  • Introduce the basic elements of typical communication systems.
  • Provide an understanding of bandwidth, as it applies to signals and transmission channels.
  • Discuss digitisation of signals and how it affects their properties.
  • Understand the basic elements of analogue and digital modulation schemes.

Objectives

As specific objectives, by the end of the course students should be able to:

  • Describe the key elements of a communication system.
  • Understand analogue modulation, and discuss the merits of amplitude and frequency modulation, and their power and bandwidth requirements.
  • Understand how digitisation affects the characteristics of a signal; in particular, the separate effects of sampling (in time) and quantisation (in amplitude).
  • Analyse the trade-off between quantisation rate and the quality of digital representation.
  • Understand the basic principles of digital modulation, be familiar with the design choices involved, and analyse the performance of modulation schemes in terms of error probability and data rates.
  • Understand the need for coding, and encode and decode bits using simple error-correcting codes such as repetition and Hamming codes
