In this paper, we investigate the problem of modelling the multi-path fading channel using maximal ratio combining technique as a spherically invariant random process. The spherically invariant random process is known to have many Gaussian-like properties and to be appropriate for modelling some practical fading environments. To be more specific, the K-distribution, which is known to be a spherically invariant random process, is chosen to model the multi-path fading channel. The new expressions of probability density functions and outage probabilities of signal-to-interference ratio are derived for the cases of equal mean powers and different mean powers of interferers. Some numerical results were done to show the behaviors and the performance of the proposed systems.
