Outage probability of cellular radio systems using maximal ratio combiningin the presence of multiple interferers

In mobile radio systems, antenna diversity is used to combat fading and I e duce the impact of cochannel interference. In this paper, we derived a new expression for probability density functions of the signal-to-interference- plus-noise ratio and apply it to analyze the outage probability (OTP) for a maximal ratio combining diversity system when multiple cochannel interfere rs are present, Numerical results showing the impact of the number of anten na elements, the number of cochannel interferers, and signal-to-noise ratio on the OTP are presented. Simulation results validating the analytical res ults are also presented.
