Module overview
- To expand knowledge of techniques for information transmission via discrete (digital) channels, which have a wide area of applications, i.e. distributed computer systems, instrumentation and control systems, as well as communication systems of all types.
- To introduce the basic concepts and applications of information theory and show its importance.
- To develop skills in communications performance evaluation and digital transmission system design.
- To concentrate attention on the application of the various analytical techniques.
- To link theoretical concepts with cutting edge industrial standards.
