We study the performance of a DS-CDMA blind multiuser detector in multipath Rayleigh fading channels for high data rates where the delay spread can be larger than one symbol duration. We study blind recursive least squares (RLS) detectors with an additional constraint on the energy of the filter tap weights. This constraint prevents the cancellation of the desired signal in case the estimated subspace of the desired signal suffers from a mismatch. Simulations show that in cases of high signal to interference and noise ratios (SINR) as well as in cases of severe inter-symbol interference (ISI), our proposed detector is superior to previously proposed detectors for multipath channels
