This paper presents the performance of Groupwise Successive Interference Cancellation (GSIC) in a DS-CDMA system with multiple data rates (multirate). The performance is evaluated both in AWGN and Rayleigh fading channels. In the GSIC scheme users with the same data rate are grouped and detected, using either a matched filter or a PIC receiver, interference between the groups is cancelled in a successive order. The results show that in a multirate system the GSIC yields a better performance thanthe PIC receiver. Further a delay error of 0.1 T{sub}c is found to be tolerable.
