Outage Probability in η-μ/η-μ and κ-μ/η-μ Interference-Limited Scenarios

In this paper exact closed-form expressions are derived for the outage probability (OP) in scenarios where the signal of interest (SoI) experiences eta-mu or kappa-mu fading, the interfering signals are subject to eta-mu fading and the background noise can be neglected. With the only assumption that the mu parameter is a positive integer number for the interfering signals, the derived expressions when the SoI is either eta-mu or kappa-mu distributed are given in elementary terms for maximal ratio combining (MRC) with independent branches. If the pre-combining SoI power signals are eta-mu distributed with their corresponding mu parameters being positive integer or half-integer numbers, the previous analysis is extended for spatially correlated MRC at the receiver.
