Level Crossing Rate of Next Generation Wireless Systems with Selection Combining in the Presence of k-µ Fading and Interference: Derivation and Simulation

In this article, level crossing rate (LCR) of new generation wireless communication system with selection combining (SC) receiver, with an arbitrary number of branches, will be evaluated. The received signal suffers from short-term fading and co-channel interference (CCI), where both are κ-μ distributed. SC receiver is used to reduce fading influence to the system performance. For described interference, LCR of the signal to interference ratio (SIR) at the output of SC receiver will be derived. From obtained expression for LCR, average fade duration (AFD) of the proposed telecommunication system can be calculated. The impact of fading parameters on the LCR will be analyzed. Thereafter, the Graphics Processing Unit (GPU) accelerated simulation and linear optimization for planning an optimal 5G mobile network within a smart city will be implemented. This program provides significantly faster calculation of system performance, such as LCR, for the wireless channels under the influence of such defined obstructions.
