Performance Analysis and Simulation of H-S/MRC using M-ary Digital Modulation Technology

Hybrid Selection / Maximal Ratio Combining is a diversity combing scheme where Lout of N diversity branches are selected and combined using Maximal Ratio Combining (MRC). This technique provides improved performance over L branch MRC when additional diversity is available. It is denoted such hybrid schemes as H-S/MRC-L\N. in the context of coherent wideband CDMA systems, these systems offer less complex receivers than the conventional MRC receivers since they have the fixed number of fingers independent of the number of multipath. In this project the exact expressions for the Symbol Error Probability (SEP) are derived for Hybrid Selection/Maximal Ratio Combining wireless systems in multipath fading environment. Coherent detection of several types of M-ary modulations is considered.
