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.
