Teaching

  • AT-M53 Lasers and applications

    The aim of this module is to present an advanced treatment of lasers and their applications to manufacturing, medicine, environmental sensing and security.

  • AT-M56 Digital Communications

    This module presents the basic theory needed and used to implement most of the modern optical communication systems currently in use. It considers noise, optimum filtering, modulation formats and their optimal under various constraints and the design of an optimum receiver. The module also gives an exposure into formation theory, coding and coded modulation. It forms a good basis for communication system design and for possible exposure into more specialized advanced topics in communication. Key focus will be on digital communications including optimum receiver design, synchronization, channel capacity, spread spectrum and error detection/corrections

  • AT-M58 MSc Dissertation - Communications Engineering

    After passing Part One students will need to conduct a research project and write a dissertation. The module aims to develop fundamental research skills. It comprises the development of supervised research work leading to a dissertation in the field of the Master's degree programme. The specific research topic will be chosen by the student following consultation with academic staff.

  • AT-M76 Wireless Communications

    The module introduces statistical signal processing. Specifically, one third is devoted to introduction of estimating random and non-random parameters. The second-third of the module introduces convex optimization. In the last part, signal processing techniques are illustrated on problems in optical wireless communications.
