Performance of two-way AF relaying with energy harvesting over Nakagami-m fading channels

In this study, the authors consider a two-way amplify-and-forward communication system over Nakagami-m fading environments, where an intermediate relay node harvests energy from its surrounding radio frequency environment using an energy harvesting technique. They propose a novel derivation approach to obtain exact expressions for user outage probability, system outage probability, and upper bound on system ergodic capacity per unit bandwidth over Nakagami-m fading channels. Monte-Carlo simulation results under Matlab software packages match the proposed analytical analyses confirming the correctness of the proposed derivation approach and the advantage of the system under consideration.
