Objectives
This module gives students an introduction to various layers in modern communications networks and how the Internet works. It provides the student with skills to apply programming tools (MATLAB) to model communication signals and systems. It also introduces familiarity with the technical concepts of both wired and wireless communication networks.Learning outcomes
On completion of this module students should be able to:
1. Explain of the principles behind the organisation and operation of communications networks.
2. Describe the layered structure of communications networks and discuss the role of each layer.
3. Analyse and solve well-defined problems involving basic communications signals.
4. Use programming tools to model some of the basic signals, components and applications of communications systems.
5. Use simulations to identify the technical challenges in both the design and implementation of modern communications networks.
6. Describe the operating principles of basic communication systems and networks, including communication channels (wired and wireless), analogue and digital signals, the radio spectrum, basic modulation and coding techniques.
7. Identify the basic modules of a typical communications system and classify the performance of various communications systems.
8. Apply mathematical and computational methods to analyse basic communications signals and functions, including analogue-to-digital conversion, modulation and error-correction.
9. Discuss the key features of a representative range of communications systems.
