Impact of hardware impairments in AF relaying network for WIPT: TSR and performance analysis

In this paper, we examine amplifying and forwarding (AF) based cooperative networks and analyze the impact of hardware impairments at the relay node on optimal throughput. In particular, the outage probability performance under hardware impairments for Rayleigh fading channels is presented in case of wireless information and power transfer (WIPT) technology. In addition, we evaluate clearly the system's performance under impact of time switching factors in time switching based relaying (TSR) protocol, level of hardware impairment and energy conversion efficiency. Finally, the Monte-Carlo simulation's result verifies the analysis in physical receiver with the acceptable hardware impairments level in order to approach the best quality of wireless communication.
