Multi-stage serial interference cancellation for DS-CDMA

The performance of multi-stage serial interference cancellation (MSSIC) for DS-CDMA has been evaluated. It is shown that linear MSSIC is asymptotically equivalent to decorrelation, but performs better than the decorrelator for a limited number of stages. However, non-linear MSSIC clearly outperforms linear MSSIC, especially in a multi-ray environment, where the linear scheme loses much of its near-far resistance
