DS-CDMA, PIC, Non-gaussian noise, multiuser detector.
In this paper, we propose a novel multi-user detector that
mitigates the MAI and diminishes the effects of the nongaussian noise in a DS-CDMA system through nonlinear parallel interference cancellation (PIC) techniques.
Results obtained by simulation show that the proposed
detector significantly improves the performance when
compared with a simple PIC. Even more, it improves the
performance of the single user system that uses a detector
designed for gaussian noise. All the improvements are at
the cost of only a slight increase in the implementation
