Abstract

In this paper we present two new, reduced complexity algorithms for multistage detection of direct sequence code division multiple access (DS-CDMA) signals in additive white Gaussian noise (AWGN) channels. The selective and successive selective multistage detection algorithms are designed to reduce the amount of computation performed by the conventional multistage detection algorithm while providing roughly the same bit error rate performance. Bit error rate performance of the new algorithms is determined via Monte Carlo simulation.
