Abstract

Using the unified expression as devised by Wojnar, an analytical framework is presented to determine the end-to-end error performance of coherent and non-coherent binary modulation schemes with dual-hop relay transmission in amplify-and-forward (AF) mode under average power scaling (APS) and instantaneous power scaling (IPS) constraints and operating over independent, non-identical flat Nakagami-m fading channels. Generalized closed-form expressions for the bit error probability (BEP) have been obtained following the cumulative distribution function (cdf)-based approach for a dual-hop relay link with single antenna nodes. Moreover, we derive a unified closed-form solution for the BEP when selection combining (SC) is employed at the IPS based multi-antenna relay to diversity process the signals.
