Performance Analysis for Optimum Combining with Unequal Power Rician Fading Interferers

We investigate the optimum combing system of a Rician fading signal with unequal power Rician interferers and thermal noise. Based on the statistical characteristics analysis of the output SINR, we derive a close form upper bound for the symbol error probability of M-ary phase-shift keying. Simulation results demonstrate the tightness of the derived bound.
