This paper introduces an improved parallel interference cancellation algorithm in a DS/CDMA communication system. Because of the lack of the energy information of interfering signal in the conventional parallel interference cancellation (PIC) algorithm, the detection performance of the weak signals is not improved. The algorithm introduced in this paper takes advantage of the virtue of successive interference cancellation (SIC) algorithm and improves greatly the detection performance of weak signals by reducing the error of multi-access interference estimation through classifying the signals. Bit error rate of this improved algorithm has theoretically been analyzed in detail. Simulation results have been given for a multitude of different situations. Finally, it is concluded that the performance of this new algorithm is more desirable than that of the conventional one.
