Abstract

In this article, we propose a new hybrid interference cancellation (HIC) receiver for multirate DS-CDMA system based on multiple processing gain (MPG). This improved HIC receiver divides the active users with different data rates into a number of groups, where each group consists of users with different data rates. First, the groupwise parallel interference cancellation (GW-PIC) is performed among the groups, and is followed by the successive interference cancellation (SIC) within each group. We derive the bit error probability (P_b) of this HIC scheme. The P_b, of the HIC receiver in AWGN channel is better than that of the adaptive multistage PIC or conventional SIC receiver.
