Performance Analysis Over Unified Generalized Composite Fading Model

This paper utilizes the unified signal-to-noise-ratio (SNR) composite distribution of alpha-kappa-mu/lognormal (LN) as well as alpha-eta-mu/LN fading channels, i.e., generalized/lognormal (GL) distribution to derive and analyse different performance metrics of digital communication system. Specifically, for coherent as well as non-coherent modulation techniques the average symbol error probability (ASEP) expressions using maximal ratio combining (MRC) diversity method are derived and utilized to carry out the asymptotic analysis of ASEP. Other metrics such as channel capacity and outage probability are also deduced and the influence of different multipath and shadowing parameters on system performance is further examined. Analytical results are supplemented with numerical results as well as Monte-Carlo simulations for validating our analysis.
