Performance simulation for LCR of 5G wireless system with L-branch SC receiver in k-µ fading and Nakagami-m interference channel

In this paper, statistical characteristics of a wireless 5G communication system with an L-branch selection combining (SC) receiver, are studied. The signal undergoes a small-scale κ-μ fading and Nakagami-m co-channel interference (CCI). We implement the SC receiver to reduce the effects of multipath fading to both outage probability and bit error probability. For the given conditions, level crossing rate (LCR) of the signal to interference ratio at the output of SC receiver is evaluated. The derived expression can be used to evaluate average fade duration (AFD) of the proposed radio communication system. The impact of the Rician factor and the short-term Nakagami-m fading severity parameter on the level crossing rate is discussed. Furthermore, we implement the Graphics Processing Unit (GPU)-accelerated simulation and linear optimization for planning the optimal 5G mobile network within a smart city. The programme results in noticeable increase in the rate of calculations of LCR for the communication channel under described conditions.
