“…1, we consider a three-terminal twoway DF relay network, where terminal A communicates with terminal B via an energy-constrained relay R. Each terminal has a single antenna and operates in the half-duplex mode. We assume that no direct link exists between A and B due to severe path loss and shadowing [21]- [24]. Channels are assumed to be reciprocal and quasi-static, and subject to path-loss Rayleigh fading.…”

Wireless energy harvesting (WEH) has been recognized as a promising technique to prolong the lifetime of energy constrained relay nodes in wireless sensor networks. Its application and related performance study in three-step two-way decodeand-forward (DF) relay networks are of high interest but still lack sufficient study. In this paper we propose a dynamic powersplitting (PS) scheme to minimize the system outage probability in a three-step two-way energy harvesting DF relay network and derive an analytical expression for the system outage probability with respect to the optimal dynamic PS ratios. In order to further improve the system outage performance, we propose an improved dynamic scheme where both the PS ratios and the power allocation ratio at the relay are dynamically adjusted according to instantaneous channel gains. The corresponding system performance with the improved dynamic scheme is also investigated. Simulation results show that our proposed schemes outperform the existing scheme in terms of the system outage performance and the improved dynamic scheme is superior to the dynamic PS scheme.Index Terms-Simultaneous wireless information and power transfer, two-way decode-and-forward relay, dynamic power splitting, system outage probability.

“…This motivates us to consider the assumption of perfect CSI. 3 In this work, it is assumed that the transmission time length of the A-R link equals that of the B-R link, the same as in [9], [15], [16]. It is worth pointing out that allowing different time lengths for the A-R and B-R links can further improve the performance of the SWIPT enabled two-way DF relaying network, which is beyond the scope of this paper and will be considered in our future work.…”

This paper focuses on the design of an optimal resource allocation scheme to maximize the energy efficiency (EE) in a simultaneous wireless information and power transfer (SWIPT) enabled two-way decode-and-forward (DF) relay network under a non-linear energy harvesting model. In particular, we formulate an optimization problem by jointly optimizing the transmit powers of two source nodes, the power-splitting (PS) ratios of the relay, and the time for the source-relay transmission, under multiple constraints including the transmit power constraints at sources and the minimum rate requirement. Although the formulated problem is non-convex, an iterative algorithm is developed to obtain the optimal resource allocation. Simulation results verify the proposed algorithm and show that the designed resource allocation scheme is superior to other benchmark schemes in terms of EE.

“…The performance of dual‐hop decode‐and‐forward (DF) relaying networks with wireless EH at the relay node over generalized η ‐ μ and κ ‐ μ fading channels was analyzed in the work of Badarneh et al Son and Kong proposed a two‐way DF scheme with an EH relay, where the relay node applies the PSR protocol and uses digital network coding to combine the decoded data before forwarding it to the source node. Van et al proposed a three‐step scheme for DF relaying in an EH network. The performance of the proposed scheme is analyzed in terms of outage probability and throughput.…”

Space modulation techniques (SMTs) are a group of multiple‐input–multiple‐output wireless systems in which the spatial indexes of transmit antennas are utilized to convey additional information bits. The SMTs promise significant enhancements in terms of spectral and energy efficiencies and attract significant research interest in literature. Several SMTs have been proposed including spatial modulation (SM) and quadrature SM. In this study, the performance of dual‐hop decode‐and‐forward relaying SM and quadrature SM in the presence of wireless power transfer is analyzed and thoroughly discussed. Specifically, we derive exact closed‐form expressions for the pairwise error probability (PEP). In addition, we derive simple and accurate asymptotic expressions for the PEP at high signal‐to‐noise ratio, which provides insight into the influence of different system parameters. The obtained PEP expressions are then employed to evaluate the overall average bit error rate (BER). It is worth highlighting that the derived expressions are unified in the sense that they are valid for the aforementioned SMTs and for two well‐known practical energy harvesting protocols, namely, power‐splitting receiver and time‐switching receiver. In addition, we derive a unified closed‐form expressions for the outage probability and achievable throughput at the destination node. The impact of diverse system parameters, such as the power‐splitting factor, the energy‐harvesting time factor, and the distance between the source and the relay nodes, on the overall system performance is studied. The accuracy of the analytical derivations is validated through Monte Carlo simulations results.
