Optical Wireless Communications

The use of optical signals for wireless transmission has become established as an alternative to radio frequency (RF) transmission. This is particularly true where RF usage is not possible. Two areas of interest that fit this description are (a) underwater transmission and (b) intravehicular communications. In both of these areas, the Communications Research Group is at the forefront of UK research activity. Therefore, applications are particularly welcomed that address aspects of the determniation of the performance of coding methods, modulation schemes and protocols for these channels.


Nanoscale Communications

Design and manipulation of objects at the nanometre scale is now established as a revolutionary technology. To date, the process of building machines and artefacts at the nanoscale has been the theme of the vast majority of the work performed. Clearly, the interconnection of these future devices will be crucial to their operation but this aspect has surprisingly received scant attention. In this work, the biologically inspired communication possibilities will be investigated and modelled to predict the performance of future nanocommunication networks.


Network Coding and Error Correction

The idea that nodes in a communication network can do more than just forward the traffic that they see has become established in what is known as network coding. Forward error correction is employed in current highly effective ways to deliver data across modern communication networks. The design of network codes with error correcting properties is a natural next step in delivering efficient and robust communication systems. The discovery of good network error correcting codes is a difficult problem and one that is very suitable for a PhD.
