This letter deals with the performance evaluation of a pilot aided method for estimating channel parameters in wideband code division multiple access (WCDMA) communication systems. Unlike previous approaches, a successive interference cancellation algorithm is used to reduce multipath and multiuser interference caused by pilot signal replicas on the channel parameter estimation, and on the detection of the information bearing signals. Comparisons with the ideal case of perfect knowledge of the channel parameters and the classical channel parameter estimation algorithm have highlighted the good performance of the proposed approach.
