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.
