Abstract

This paper considers the performance of Successive Interference Cancellation (SIC) applied to a DS/CDMA micro-cellular environment, by employing a circular geometry and expressing the BER of a DS/CDMA system with SIC to analyse the effect of phase estimation error and tracking error. Since the optimal DS/CDMA multi-user detector is too complex, much work is currently being done in order to see whether a practical version is feasible. Among the issues that need to be addressed are departures from ideal assumptions that may affect the performance. We derive results for the performance degradation that a SIC scheme experiences due to phase estimation error and tracking error for a multi-cell DS/CDMA system. Results are displayed as a functions of the phase estimation error and tracking error. It is shown that the interference canceller still retains a performance advantage over the conventional detector.
