Signal Processing for Communications

Our major research objective is to use signal processing to contribute towards the development of innovative algorithms, performance analysis and simulation/implementation of advanced, wireless communication systems.  A variety of research activities are undertaken ranging from theoretical work to application driven algorithm design, with the results published in the highest quality IEEE international journals and conferences.  We seek to maintain and develop a vibrant research group that engages in and develops the very latest signal processing theories and applies them to real-life communication problems.

Our research activities are wide ranging and cover most aspects of the application of mathematical analysis and signal processing to enhance the performance of wireless communication systems.  Current and past research projects include new channel estimation and equalization solutions for rapidly fading wireless channels; advanced frequency and phase synchronization in single-carrier and multi-carrier systems; signal processing for doubly selective (time/frequency) wireless channels; MIMO signal processing – including MIMO OFDM, new precoding structures/beamforming, advanced multiuser detection and enhanced diversity reception; cooperative signal processing – including new wireless channel fading models, opportunistic relaying algorithms and ergodic capacity calculations; cognitive radio networks – including application of stochastic geometry for performance analysis, cooperative sensing, energy detection in the presence of parameter uncertainties; location/positioning – novel location/positioning/direction of arrival algorithms and GNSS signal processing; other general applications of signal processing – including cross layer, ultra-wideband and sensor signal processing, Bayesian estimation of multipath, ballistic missile identification via precession frequency extraction, etc.

We are funded from a variety of sources to support the group’s research students and other activities.  These include the Royal Society (UK), the Royal Academy of Engineering (UK), Army Research Labs (USA), the Engineering and Physical Sciences Research Council (UK), Higher Education Commission (Pakistan), Mexican National Council for Science and Technology (CONACYT) and the National University of Defense Technology (China).
