Abstract – In this paper, we develop a mathematical framework for analyzing a Partitioned Generalized Selection Combining (PGSC) scheme for selective Rake (SRake) receivers that adaptively combines a “selected subset” of received signals based on the strongest SNR. We show that a trade-off between the receiver circuit complexity and required level of performance can be achieved using PGSC. Bit error rate performance of various digital modulation schemes in conjunction with coherent and non-coherent PGSC receivers are analyzed for all common multipath fading channel models (Rayleigh, Rician and Nakagami-m) with the assumption of independent and identical fading. It is observed that for large number of received signal paths, PGSC offers comparable performance to that of GSC but at reduced selection circuit complexity. Also, coherent and non-coherent PGSC receivers offer comparable performance with the former having slight diversity gain over the latter.
