Professor White's research interests and activities lie in the general areas of statistical signal processing and control. Current projects include :

1. Statistical modelling and estimation for hidden reciprocal chains (HRCs)

HRCs are non-causal generalisations of hidden Markov chains and are one-dimensiona Markov random fields, although reciprocal processes are not, in general, Markovian. In this research, we investigate modelling, optimal state estimation, parameter estimation and model classification for HRCs. Applications addressed include "destination-aware" target tracking and the forensic analysis of "pattern-of-life" problems. This work is a collaboration with Dr Francesco Carravetta (IASI-CNR, Italy).

2. Signal subspace methods for sensor array processing of temporally correlated signals

This research is motivated by the question of whether temporal correlation in signals incident of a sensor array can be used to improve source localisation and classification. Advances in computational power mean that previously neglected techniques such as maximum likelihood estimation now become feasible. Recent results concerning the asymptotic consistency of certain estimators (Generalised Statistical Analysis) has also raised the question of whether these approaches can be used in signal subspace based methods such as ESPRIT. This project investigates a range of questions related to these two problems. Collaborators : Prof Peter Sherman (Iowa State Univ., USA), Defence Science and Technology Organisation Australia.

3. Markov Decision Processes and State Aggregation

This work is concerned with the development of sub-optimal control strategies for very large Markov decision processes, where state aggregation is used to reduce dimensionality. Models considered include Quasi Birth-Death processes and optimally lumped processes.

4. Signal processing for GPS interference mitigation

Funded by an ARC Linkage grant, and building on previous work conducted in the School, this work is concerned with localisation and mitigation of jammers/spoofers in the GPS bands. Much critical infrastructure (e.g. aviation, ports, mining) relies on GPS localisation and the issue of dealing with deliberate or unintentional interference is very important. This project teams with the University of NSW and GPSat Systems.

5. Adaptive games and applications to Communications Systems

In this work, we consider resource allocation in communications networks from a game theoretic point of view. In particular, we examine regret-based reinforcement learning algorithms which, although primarily decentralised, do allow both limited feedback from the resource providers, and the ability for users to form coalitions (i.e. co-operate) to improve performance. These techniques are generic and can be applied in other applications, for example the energy market.
