Outage probability of optimum combining and MRC in a Rice fading channel with cochannel interference
Chirasil Chayawan, Valentine A. Aalo · 2002
Antenna diversity is a commonly used technique to combat fading and reduce the effect of interference in mobile radio systems. In this paper, we study the outage probability of optimum combining (OC) and maximal ratio combining (MRC) in a flat-fading Rice channel in the presence of multiple Rayleigh distributed cochannel interference. The analysis assumes that the environment is interference-limited so that the effect of thermal noise is ignored and that the number interferer is larger than the number of antenna elements. Numerical results showing the impact of the number of antenna elements, the number of cochannel interferers, and the Rice-factor are presented for both OC and MRC system.
