Abstract

A new technique is proposed for robust multiuser detection in channels with impulsive noise. The method is a modification of traditional nonlinear multiuser detection techniques, whereby the nonlinearity is now positioned between the multiplier and the summation, within the correlator, instead of preceding it. This is then extended to provide a modification to the two-stage nonlinear detector proposed in Weng et al., (1997). Simulation results show that the use of this technique increases multiple access interference (MAI) rejection. Near-far effects are also investigated
