摘要
The radio frequency energy harvesting (RF-EH) technique provides a potential way to power the battery-constrained wireless devices in the future generation wireless networks. In this paper, we investigate a dual-hop decode-and-forward (DF) cooperative network with RF-EH using non-linear hybrid power-time-splitting (PTS) based model. In the proposed system, the best relay is obtained by considering the instantaneous signal-to-noise ratios (SNRs) of source (S) to relay (R) links using three selection schemes, namely, absolute SNR-based selection, normalized SNR-based selection and random selection. Considering the DF protocol at R, we evaluate the outage and throughput performances of the system over independent and identically distributed Rayleigh fading channels. The derived results are validated through Monte-Carlo simulations.
