Module summary

This module extends the theories and concepts covered in the Communication Systems module in the autumn term. The Digital Communication Systems module will have a deeper look at the main concepts of wired and wireless communication systems, architectures of transmitters and receivers that solves the general issues in such communication systems including DSP implementations and the tools to analyse the performance of them.

Module will run

Occurrence Teaching cycle
A Spring Term 2021-22 to Summer Term 2021-22

Module aims

Subject content aims:

  • To provide an understanding of the principal issues and techniques involved in baseband data transmission
  • To introduce the most common forms of passband modulation, both linear and exponential, their characteristics and error rates
  • To introduce the student to radio modem principles and architectures, and provide the tools to analyse weak and strong signal handling performance
  • To show how key receiver building blocks can be implemented in both hardware and DSP implementations

Graduate skills aims:

  • To develop skills in the selection and application of appropriate numeric and algebraic techniques

Module feedback

'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme.  We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments.

A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback.  This can be found at

The Department of Electronic Engineering aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme.  In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work.  Students are provided with their examination results within 20 working days of the end of any given examination period.  The Department will also endeavour to return all coursework feedback within 20 working days of the submission deadline.  The Department would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback.  The Department will endeavour to keep such delays to a minimum.  Please note that any marks released are subject to ratification by the Board of Examiners and Senate.  Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
