Maximum a posteriori discrete-time rake receiver using realistic estimated channel state information and operating on diffuse multipath channels

We propose a maximum a posteriori structure of the discrete-time rake receiver, which optimally takes into account the estimated nature of the channel state information. The performance of this structure is evaluated through simulation results and compared to that of the conventional discrete-time rake receiver with perfect and estimated discrete-time channel state information. A diffuse multipath channel with classical Doppler power spectrum and exponentially decaying multipath intensity profile is used in this evaluation.
