Research interests
Source and Channel Coding, Coding with Side Information, Information and Coding Theory. I am especially intrigued by the rate loss in some cases of side information (e.g. binary symmetric) and not others (e.g. Gaussian), the links with correlation and random variable dependence and the central role of Gaussian distributions.
Lossless Data Compression, correlated source coding (Slepian-Wolf and Wiener-Ziv practical code design).
Signal Processing (particularly for communications, image and video processing, more currently medical image processing for early detection of tumours).
Satellite and wireless communications as applications of signal processing, coding and modulation design.
Communications channels, practical code design and theoretical limits. Design of capacity approaching codes for channel and source coding, with or without side information.
The link between iterative decoding of communications codes and neural networks (belief propagation).
Last (but not least) I enjoy writing complex communications algorithm simulations in C++, including fast searching for good permutations, the wonders of tree search, finding minimum distances and identifying trapping sets in iterative decoding, visualising extrinsic information exchanges, providing a practical check for my ever expanding interest in mathematics, probability distributions and information theory. For all that and more, I found C++ an extremely powerful tool.
