Communication Systems and Digital Communications - ELE00078H
Module summary
The Communication Systems module provides you with a detailed understanding of how wired and wireless communication systems work, from theoretical concepts through to the design of practical radio systems and networks. Topics include: information theory; wireless link design; signals, baseband and passband radio modulation and demodulation; transmitter and receiver architectures, networks and protocols.

Module aims
-
To introduce the basic knowledge necessary for transmitting and receiving information using today's communication technologies.
-
To introduce analogue and digital communication systems and networks, emphasising the transition from analogue to predominantly digital 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.
Graduate skills aims:
-
To develop skills in the selection and application of appropriate numeric and algebraic techniques.
Module learning outcomes
After successful completion of this module, students will be able to:
- Assess the information content of a source, understand the rate of information transfer across a communication channel and how this relates to capacity.
- Represent information and systems as time-domain or frequency-domain functions with an understanding of the equivalence between these domains
- Discuss the basic theory and operation of analogue communication systems, e.g. AM and FM modulation.
- Discuss the fundamentals of digital communication systems, especially baseband signalling, digital modulation and error control coding.
- Produce a communications link budget and analyse and design simple analogue/digital communications systems.
- Explain the principles of networks and the underlying protocols, including medium access control and automatic repeat request schemes.
- Evaluate the design, operation, application and performance of a selection of wired/wireless communication systems using appropriate tools.
Graduate skills learning outcomes
After successful completion of this module, students will be able to:
- Explain and evaluate advanced technical concepts concisely and accurately
- Select, adapt and apply a range of mathematical techniques to solve advanced problems
- Demonstrate skills in problem solving, critical analysis and applied mathematics

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.
The School of PET 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. The School will endeavour to return all exam feedback within the timescale set out in the University's Policy on Assessment Feedback Turnaround Time. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School 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.
Formative Feedback
Labs will allow you to design, model/implement and evaluate communication systems and you will receive verbal help and feedback in all the aspects during the session.
Tutorial questions at the end of each main section help you to gain feedback on your understanding of the key concepts covered in the lectures.
Structured solutions to questions sheets help you not only to gain feedback on your understanding of the key material covered in the lectures, but also to identify the steps you have done correctly/incorrectly.
Workshop sessions will allow you to work through questions and to receive verbal feedback of your work
Questions posted to the VLE forum/wiki will be answered as soon as possible by the module coordinator and also an opportunity for the peers to contribute/learn/discuss.
Summative Feedback
Marks will be provided for the exam.
