Derivation and Simulation of Outage Probability for 5G Wireless System with L-branch SC Receiver Influenced by Rician Fading and Nakagami-m Co-channel Interference

The performance of wireless 5G communication system with L-branch selection combining (SC) receiver, will be analyzed in this article. The transmitted signal suffers from a small-scale Rician fading and Nakagami-m co-channel interference (CCI). The SC combiner with L branches is being implemented in the receiver to reduce the impacts of multipath fading to the system performance as outage probability (P
out
), bit error probability (BEP), … The expression for the outage probability based on the signal to interference ratio (SIR) at the output of the SC receiver will be derived. The influence of parameters (Rician factor, Nakagami-m fading severity parameter, the mean values of the signal and interference powers, the number of the SC combiner input branches) on the P
out
will be examined. Then, the Graphics Processing Unit (GPU) accelerated simulation and linear optimization for designing the optimal 5G mobile networks will be used. This program provides significantly faster calculation of the system performance, such as P
out
, for the wireless channels and maximize the Quality of Service (QoS) for a 5G wireless systems under the influence of mentioned nuisances.
