摘要：

Channel estimation problem for TD-SCDMA parallel interference cancellation (PIC) receiver is considered in this paper. Accurate information of channel impulsive response (CIR) is the key to performance of receivers. Successive interference-cancellation based estimation method is proposed, and it's compared with conventional correlation method and joint channel estimation method by link level simulation with COSSAP platform. The simulation results show that the suggested channel estimator can provide more accurate estimates than conventional method under high-speed vehicular channel.
