Key module for

MSC H64112 Global Communication Systems,
MENGH642 Communications Engineering

Module description

The module will provide an understanding of the principles and practices of modern digital communication systems. It reviews baseband and band-pass techniques, pulse code modulation, and studies modern methods of transmission, including multiplexing and multiple access. The module introduces wired and wireless transmission techniques including those used in current broadcast and mobile communications systems. Representative transmission systems selected for study include digital radio, television and WiFi and communication satellites. Operation principles, link budgets and design of basic components of transmission systems are described and discussed in detail.

Module aims

This module aims to define the principles and practices of modern digital communication systems. It introduces a number of standard techniques for transmission including multiplexing and multiple access for wired and wireless transmission systems.

Module learning outcomes

After completing this module, students will be expected to be able to:

1. Explain the principles of baseband and band-pass digital transmission.
2. Assess bit error rates of digital communication systems.
3. Discuss physical layer aspects of radio networks.
4. Design and explain antenna principles.
5. Develop an RF link plan for reliable digital transmission and asses failure probability for given system parameters.
6. Describe practices of modern multiplexed transmission systems.
7. Discuss the principles of digital transmission over cable and RF networks, and explain examples of current practices.
8. Explain satellite and terrestrial systems design.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
