Abstract

We derive the optimum and suboptimum selective rake receivers (SRRs) for fading environment exhibiting impulsive nature. Simulation results confirm that, when the noise is impulsive, the SRRs designed for impulsive noise offer performance improvement over those optimized for Gaussian environment. The suboptimum SRR is observed to exhibit almost the same performance as the optimum SRR.
