Determination of LCR for Multi-branch SC Receiver under the Effects of α-κ-µ Fading and Weibull Co-Channel Interference

To face confront the requirements of 5G wireless communication systems, there are still many challenges such as increasing capacity and data rate, the less delay, greater spectral and energy efficiency, ... Also, the goal is to increase transmission reliability by reducing the errors and the outage probability. For that purpose, the characteristics of a wireless system in the presence of α-κ-μ fading and Weibull co-channel interference (CCI) are studied in this work. The multi-branch selection combining (SC) receiver is implemented for reducing the effects of multipath fading and co-channel interference. The level crossing rate (LCR) of the signal to interference ratio (SIR) at the output of the receiver is derived and graphically presented. The fading parameters' influence is analyzed based on drawn graphics.
