Performance analysis of partial parallel interference cancellation in synchronous DS-CDMA systems over frequency selective fading channels

In this paper, we investigate the performance of partial interference cancellers in forward link DS-CDMA over time-invariant frequency selective fading channels. An analytical tool to find the bit error probability is presented. We also compare the analysis with computer simulation. The results show that the presented approximation can predict the performance at low to moderate signal to noise ratios.
