摘要：

The channel-tracking mode performance of the front-end (FE) processors which were developed in a companion paper [1] is determined through approximate analysis and computer simulation, A general model for the FE processing, which encompasses these representative FE's, is assumed, Previous analysis techniques are extended to include the effects of FE processing. The specific system analyzed consists of a Rayleigh-fading, diffuse multipath channel with several data pulse shapes considered, An adaptive maximum likelihood sequence estimation (MLSE) algorithm based on the per-survivor processing (PSP) technique is analyzed and compared to an algorithm based on correct symbol feedback. The results show that significant performance degradation is suffered when suboptimal FE processing is used, The limitations of the results and the models used are discussed.
