Full Module Description

Using a combination of theory, design and practice, and drawing on the latest research and industry standards, this module provides a comprehensive introduction to modern communication systems, covering the fundamental principles that underpin the transmission of information from transmitter to receiver across a range of media. Students explore electromagnetic wave propagation, transmission lines, antennas, and wireless channels, before examining the impact of noise and key system performance metrics such as signal-to-noise ratio (SNR) and link budgets. The module then develops core concepts in sampling, quantisation, multiplexing, and digital communication, including coding, capacity limits, and bit error rate performance. Both analogue and digital modulation techniques are studied, alongside the architectures of practical transmitters and receivers. Throughout, MATLAB-based simulations and laboratory sessions support the analysis, design, and evaluation of communication systems, enabling students to link theoretical concepts with real-world engineering applications.

Please note that the University will use all reasonable endeavours to deliver courses and modules in accordance with the descriptions set out here. However, the University keeps its courses and modules under review with the aim of enhancing quality. Some changes may therefore be made to the form or content of courses or modules shown as part of the normal process of curriculum management.

The University reserves the right to make changes to the contents or methods of delivery of, or to discontinue, merge or combine modules, if such action is reasonably considered necessary by the University. If there are not sufficient student numbers to make a module viable, the University reserves the right to cancel such a module. If the University withdraws or discontinues a module, it will use its reasonable endeavours to provide a suitable alternative module.
