ELEC3480 Digital Communications & Signal ProcessingThis module is not approved as a discovery module
Objectives
This module introduces the key principles of advanced digital communications systems, including pulse shaping, channel characteristics and multiple-access techniques in cellular mobile and optical communications systems.Learning outcomes
On completion of this module, students should be able to:
- show a good understanding of the engineering principles behind the physical layer in modern communications networks;
- demonstrate extensive knowledge and understanding of the principles of digital modulation schemes such as BPSK, QPSK and QAM;
- use analytical techniques to predict the performance of communications systems;
- understand the nature of communication channels and the methods used to combat signal impairments;
- reproduce all aspects of both the design procedure, and subsequent analysis, for a representative communications system case study;
- use mathematical or other simulation tools to model the performance of a typical communications subsystem.
Syllabus
