Energy harvesting relaying using non‐ideal relaying node in Rician fading channels

Abstract

Idle nodes are used in cooperative communication to achieve performance gains. Energy harvesting (EH) technology makes cooperative communication less dependent on batteries. In this study, the performance of EH amplify‐and‐forward relaying is analysed by considering the throughput for Rician fading channels and non‐ideal relaying nodes, compared with previous works that focused on Rayleigh fading channels with ideal relaying nodes. The authors consider discrete time EH protocol and continuous time EH protocol. In addition, they derive the analytical expressions for the average throughput. Numerical results are presented to show the good performance of the system in Rician fading channels and the satisfactory performance while using the non‐ideal relaying node by examining various system parameters using the analytical expressions.
