Abstract

In this paper, the performance of DS/CDMA receiver is analyzed, which employs a cascaded interference canceller using a soft detection. The channels considered is characterized by the multipath fading which is one of the factors for the performance degradation in mobile communication systems. The idea behind the cancellation is that the co-channel interference can be regenerated at the receiver and is subtracted from the received signal. The numerical results show the improvement of BER can be obtained by the proposed cancellation scheme.
