Performance Analysis of Dual-Hop Systems with Decode-and-Forward Relays over Generalized Fading Channels

摘要

Dual-hop transmission systems employing decode-and-forward relay are studied in this paper. The examination has been done for independent, but not necessarily identical Extended Generalized-K fading channels. New, exact, closed-form expressions are derived for the outage probability, the nth moments of the end-to-end signal-to-noise ratio (SNR), and the ergodic capacity. Moreover, the average symbol error probability (ASEP) for coherent and non-coherent modulation schemes is derived. Analytical results along with simulation results are obtained with excellent agreement.
