This programme addresses the problems caused by fast fading on mobile radio channels. The effects of this fading become more significant as higher frequency bandwidths are licensed for mobile radio applications. An investigation into the effects of decision errors on directed algorithms will be conducted with particular relevance to the problems associated with code division multiple access (CDMA) diversity reception over a fast fading mobile radio channel. We aim to improve the performance of a prediction algorithms while having less need for periodic retraining using known data. The approach is to first formulate methods of determining the conditions leading to instability in a least square (LS) predictor (preliminary work has already indicated that this is feasible). Modelling the predictor algorithm as a Markov process enables the stability to be monitored and also avoids lengthy Monte Carlo type simulations. The simulation of the system will use a mobile radio multipath channel mode with fast Rayleigh fading. To improve the performance of the system we will investigate methods to constrain and adapt the prediction coefficients so that unstable conditions are avoided, but predictor performance is still acceptable. We will also consider the wider application of the results of this work.
