Working with Markov-Chain Monte-Carlo analysis for multi-user detection and applications to system identification. My work with SPM also includes hardware design and embedded software development related to the MIMO wireless testbed. I have experience in the implementation and refinement of computational algorithms and have completed a masters degree in Electrical Engineering at the University of Newcastle with a project implementing predictive current control for induction machines on an FPGA.
Projects
MCMC Multi-User Detection
The application of Metropolis-Hastings and Gibbs Sampling algorithms to CDMA Multi-User Detection. This approach offers near-maximum likelihood detection with soft-outputs. This project investigates the computational feasibility of this approach.
MCMC System Identification
Markov Chain Monte-Carlo methods are used to calculate probability density functions for parameters in dynamic systems models. By virtue of computation of the true posterior density, these methods allow accurate quantification of estimation error, even for short data lengths.
MIMO Communications Testbed
This is a hardware device designed to be used in the design and testing of wireless MIMO communications systems. It is connected to a PC via USB 2.0 or ethernet and uses an on-board FPGA to allow implementation of algorithms in logic, together with provision for multiple radio modules.
System Identification
Theoretical and empirical study of various problems in system identification. Particular attention is paid to robust estimation of Multivariable and Nonlinear systems, and to error quantification.| Journal Papers |
