On Performance of Wireless-Powered FD Relaying Network with Imperfect SIC and Hardware Impairments

In this paper, we analyze the performance of a wireless-powered full-duplex (FD) relaying network over generalized Nakagami-m fading channels for 5G and beyond wireless communication systems. We employ a power beacon that provides a stable and reliable radio-frequency energy and resolves the energy-constraint problem. We also employ a time-switching (TS) receiver for simultaneous energy harvesting and information transmission. We consider the impact of residual self-interference (RSI) because of the imperfect self-interference cancellation. Further, we consider the impact of transceiver hardware impairments (HIs). For the performance analysis, we derive the closed-form expressions of outage probability, system throughput, and energy efficiency over Nakagami-m fading channels. We highlight the impact of RSI, HIs, TS factor, overall system ceiling effect, and other system parameters on the performance of the considered network. An optimal value of the TS factor is obtained for which the considered network exhibits optimum outage performance. In last, we perform the Monte-Carlo simulations to verify the derived closed-form expressions.
