The performance of optimum combining (OC) for a space diversity reception in digital cellular radio systems with a non-Gaussian multipath fading channel and multiple cochannel interferers (CCI), each having some specified average power, is examined in this paper. The fading process is specifically modeled by a process that has many Gaussian-like properties called spherically invariant random process (SIRP). In some practical fading environments, this process has been illustrated that it is capable to model the multipath fading process appropriately. An exact distribution of outage probability is eventually determined as the cumulative density function (cdf) of the output signal-to-interference-plus noise ratio (SINR) that is greater than some specified threshold, in the general case of arbitrary number of interferers N is not less than the small number of antenna elements M (M N, M=1,2).
