Abstract

In this letter, we study the performance of optimum combining (OC) and maximal ratio combining (MRC) diversity schemes in wireless digital communication systems with Rice fading and cochannel interference. New simplified closed-form expressions are derived for the probability density function (pdf) as well as the outage probability for OC and MRC when the desired signal has a line of sight and the interferers are assumed to be scattered and further away from the receiver. It is assumed that the interferers have equal powers and their number (L) is larger than the diversity order (M), i.e., L>M
