The aim of the module is to introduce the basic principles of digital communications and provide the students with knowledge and skills required in the design and performance analysis of digital communication systems.

The following topics will be covered:

  • introduction
  • digital versus analogue
  • main components of digital communication systems
  • digital baseband transmission
  • sampling
  • quantisation
  • PCM/DPCM
  • data transmission fundamentals
  • line coding
  • binary and multilevel signalling
  • multiplexing
  • detection of digital signals
  • noise in communication systems
  • inter-symbol interference
  • decision theory
  • digital modulation and demodulation
  • ASK/FSK/PSK/DPSK
  • probability of error performance and bandwidth efficiency
  • fundamentals of information theory and channel coding
  • research project and simulation work using MATLAB software tools.
