摘要：

A 3-stage coherent multistage interference canceller for DS-CDMA mobile radio was implemented and its performance in frequency selective multipath fading channel is experimentally evaluated by using a multipath fading simulator. The implemented interference canceller applied pilot symbol-assisted channel estimation for data decision and replica generation of multiple access interference (MAI). The laboratory experiment demonstrated that, as is expected, the coherent multistage interference canceller can reduce the MAI to satisfactory levels in multipath fading environment and this, improving the bit error rate (BER) performance under multiuser environment.
