WIRELESS ENERGY HARVESTING RELAYING NETWORKS UNDER IMPERFECT CSI: THROUGHPUT ANALYSIS
The purpose of this research aims to investigate an amplify-and forward-based (AF) energy harvesting (EH) system with imperfect channel state information (CSI), where twoend-nodes and one relay are operated in half-duplex mode. Power splitting-based relaying (PSR) protocol is used to transmit information from source to destination by the energy harvesting enabled relay. The authors propose that the initial power contained in the battery is...

In this paper, the authors investigate relay selection for decode-and-forward (DF) Full-duplex (FD) based wireless energy harvesting relaying networks. Considering time-switching based relaying (TSR) protocol, this investigation is concerned with the performance of maximum harvested energy relay selection (MHE-RS) scheme. In particular, this work analyzes the system performance in terms of outage probability (OP) and throughput over Rayleigh...
