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
