Description In this paper we derive and propose constrained blind DS-CDMA UWB multiuser detection algorithm to suppress the multi access interference (MAI) in multipath channels, and studied its bit error probability performance in the presence of narrowband interference. Variance of the receiver output is minimized subject to appropriate constraints. Receiver does not require spreading code knowledge of all users other than that of the user of interest. Simulation results show that bit error probability performance of the proposed algorithm is better than that of adaptive minimum mean square error (MMSE) detector in multipath channels, and much better in the presence of multipath channels with narrow-band interference.
