Module summary

In order to pass this module, students must obtain a mark of at least 30% in the final examination, as well as obtaining an overall mark of at least 40% for the module.


Introduction to telecommunications systems, mobile and wireless communications, computing and the internet.

Properties of sinusoidal signals.

Advantages/disadvantages of digital communications.

Digital signals: analogue to digital conversion, sampling; digital to analogue conversion.

Noise on communication channels

Multiplexing

Objectives

This module gives students an introduction to various layers in modern communications networks and how the Internet works. It provides the student with relevant programming tools (MATLAB) to model communication signals and systems.

Learning outcomes
On completion of this module, students should be able to:

- demonstrate a knowledge and understanding of the principles behind the organisation and operation of communications networks;
- demonstrate a knowledge and understanding of the layered structure of communications networks and showing some detailed knowledge about each layer;
- use programming tools to model some of the basic signals/elements/applications of communication systems
- appreciate, through basic case studies, the technical challenges in both the design and implementation of modern communication networks

Syllabus
