Claim One:
1. A multi-stage, Normalized Least Mean Square (NLMS) based, Parallel Residue Compensation (PRC) receiver comprising: a matched filter stage coupled to receive a multiuser signal and adapted to provide data symbols representing demodulated bit stream groupings for each user; a signal reconstructor coupled to receive the data symbols and adapted to generate modulated representations for each users' data symbols to produce a replica of the multiuser signal; an NLMS block coupled to receive the replica of the multiuser signal and adapted to compute a weighted estimation of the replica; and a parallel compensation residue (PRC) block coupled to receive the weighted estimation of the replica and the multiuser signal and adapted to generate a common residual error signal from the weighted estimation of the replica and the multiuser signal, wherein the common residual error signal is subtracted from each users' data symbols to cancel interference associated with each users' data symbols.
