On the outage probability and BER of a DF-based multi-hop system over alpha - kappa - mu and alpha - kappa - mu-extreme fading channels

摘要

This paper analyzes the performance of decode-and-forward (DF)-based multi-hop relaying communication systems over alpha - kappa - mu and alpha - kappa - mu-Extreme fading channels. Analytical formulas for the probability density function (PDF) and the cumulative distribution function (CDF) of the received signal-to-noise ratio (SNR) as well as its moment generating function (MGF) are derived. Based on the derived PDFs, novel closed-form expressions for the outage probability (OP), bit error rate (BER) under coherent and non-coherent modulation schemes are derived. Additionally, asymptotic analyses of BER based on Poincare series expansions of SNR PDFs are carried out and results show good approximations for low SNR regimes. Simulations are performed to verify the accuracy and to show the tightness of the theoretical analysis. (C) 2020 Elsevier GmbH. All rights reserved.
