Digital Communications

Module code: EG7022

This module will be delivered through a series of seminars and practical sessions, where the theoretical aspects of this module will be complemented with extensive practical exercises using Simulink based computer modelling. You will develop a broad understanding of the components of a digital communication system, together with an appreciation of the limitations of these systems and the techniques employed to mitigate the limitations.

Topics covered

• Introduction to Simulink and the Communications Toolbox
• Baseband digital transmission
• Bit error rate and signal to noise ratio
• Eye diagrams and constellation diagrams as quality diagnostics
• Bandwidth and data-rate
• Carrier and modulation methods
• The trade-off between throughput and quality
• Source coding
• Channel coding to reduce errors
• Digital communications through fading multipath channels
• Interleaving
