Abstract :
In this paper, we make use of our general results on tracking fast fading channels to study several important special cases to provide insights and explore connections with well known existing results. The following special cases are considered: quasi-static Rayleigh fading channels, fast Rician fading channels and fully correlated fast Rayleigh fading channels. In particular, the role of channel estimation errors, antenna correlation and user signal correlation on detector performance are quantified. In addition, we quantify the effect of the number of training symbols on the performance of our MAP receiver with a Kalman filter. Finally, we compare our MAP receiver with two other adaptive receivers, the adaptive channel predictor and the adaptive MMSE combiner. The study uses a combination of analysis and simulations.
