Outage probability simulation of a MIMO L-branch SC diversity system with k-µ fading and Rayleigh co-channel interference

In this paper, a wireless MIMO communication system with L-branch selection combining (SC) receiver operating over short-term k-μ fading and Rayleigh interference channel, is studied. Signal at the receiver undergoes a small-scale k-μ fading, while co-channel interference (CCI) undergoes Rayleigh fading. Analytical expression for the outage probability (P
_out
) of the signal to interference ratio at the output of SC receiver is evaluated. The impact of the Rician factor, the mean value of the signal and interference power, the number of clusters and the number of branches of the SC combiner on the P
_out
is analyzed and discussed. In a simulated environment for the described conditions, we have implemented GPGPU programming with the aim to increase the rate of calculations of fading and maximizing the Quality of Service (QoS) for a given system.
