摘要：
In this paper a new, reduced-complexity algorithm for multistage detection of direct-sequence code division multiple access (DS-CDMA) signals in additive white Gaussian noise (AWGN) channels is presented. Bit error rate performance of the new algorithm is determined via Monte Carlo simulation, and it is shown that the new algorithm, although designed to reduce computational complexity, performs better than conventional multistage detection.
