Abstract
The partial RAKE receiver (PRR) is analyzed in the presence of fading and impulsive noise. The maximum likelihood PRR for impulsive, fading channel is derived, and a suboptimum PRR with reduced complexity is obtained. It is shown from numerical results that, when the noise is impulsive, the PRRs designed for impulsive noise offer performance improvement over those optimized for Gaussian environment. It is observed that the suboptimum PRR exhibits almost the same performance as the optimum PRR.
