AB  - <p>Relaying transmission is a promising approach for enhancing the performance of wireless networks, meanwhile wireless power transfer is an emerging solution for prolonging the lifetime of energy constrained relay nodes. In this framework, the amplify-and-forward (AF) relay network consisting of a power transfer and information source, an energy constrained relay and a destination over dissimilar fading channels is taken into account. First, the relay employs the time switching-based relaying (TSR) protocol to harvest energy from the source. Accordingly, the relay supports the source transmits information to the destination. By utilizing the statistical characteristics of signal-to-noise ratio (SNR), the closed-form expressions of outage probability (OP) and average symbol error probability (ASEP) are derived. By means of the obtained result of OP, we also investigate throughput of the system for delay-limited transmission mode. Moreover, we accordingly evaluate the analysis in details and assess the performance of the considered system in various system parameters, such as energy harvesting time, energy harvesting efficiency, and relay location. Finally, Monte-Carlo simulation is also contributed to confirm the correctness of the analytical results.</p> <p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.21.5.13331">http://dx.doi.org/10.5755/j01.eee.21.5.13331</a></p>
