Abstract
In this paper, we analyze the BER performance of Groupwise Successive Interference Cancellation (GSIC) scheme in a DS/CDMA system. Groupwise Power Disparity (GPD) is considered for each group size in order to improve the BER performance of GSIC scheme. The results show that there exists an optimum GPD value that minimizes the average BER performance for a certain number of concurrent users and a certain number of group size. It is demonstrated that the complexity and decoding delay can be greatly reduced by the GSIC scheme, while the BER performance is slightly degraded.
