Abstract

In this paper, the design and analysis (by deriving the exact expression for SEP) of Hybrid Selection/Maximal Ratio Combining (H-S/MRC) is carried out. Independent Rayleigh fading diversity branch is assumed for analysis with equal Signal-to-Noise Ratio averaged over the fading channels and coherent detection of M-ary Pulse amplitude modulation (MPAM) is considered. Virtual branch technique is used. It transforms the ordered physical branches, which are dependent into independent, and identically distributed virtual branches.

Keywords

diversity reception, virtual branch technique, Rayleigh fading channel, Symbol error probability.
