Abstract

In this paper, we analyse the throughput performance for two, three and four time slot transmission schemes, (2TS, 3TS and 4TS) for two-way amplify-and-forward relaying networks, in which we use RF signal for the energy harvesting (EH) enabled relay node to assist the exchange of information. Most importantly, we derive expression for delay-limited throughput and the approximate expressions for outage probability, and we also compare these results in case of EH and non-EH. Additionally, the trade-off between the distance allocation between source to relay, and relay to destination is comprehensively investigated, in which the large scale path loss is considered to obtain the optimal throughput. Thanks to the numerical results, we consider a scenario in each scheme, where the throughput of 2TS is higher regardless of values of power splitting coefficients compared to other two schemes. Numerical results provide an interesting trade-off between the considered EH parameters in the system design, and reveal the improvement of bandwidth and power efficiency. The proposed schemes confirm that the appropriate placement of nodes can help achieve low outage probability and optimal throughput.
