This paper considers a full duplex (FD) cooperative non-orthogonal multiple access system that employs power splitting relaying (PSR)-based simultaneous wireless information and power transfer (SWIPT) technique, that is, FD-PSR-NOMA system. A single cell network is considered consisting of a base station (BS) and two pre-paired users, where the near user is configured to act as FD relay to assist the BS for information delivery to the far user. It is assumed that the far user implements maximal ratio combining to combine the direct link signal arriving from the BS and the relayed signal from the near user, to exploit the diversity advantage. Analytical expressions are derived for the outage probabilities of the downlink users, system outage probability, and the throughput of the considered network under imperfect successive interference cancellation (i-SIC). Analytical expressions are also derived for the outage probabilities and throughput of half duplex (HD) cooperative NOMA system under PSR-based SWIPT, that is, HD-PSR-NOMA system. Further, the asymptotic outage probabilities and diversity orders are derived as well. The optimal power allocation factors at the BS that minimize the system outage probabilities of FD/HD-PSR-NOMA networks are determined. Extensive simulation results are provided to corroborate the analytical findings.

“…The performance of conventional CR‐NOMA systems has been extensively analyzed in the literature (eg, References 9‐12 and references therein). Recently, the performance of EH based conventional CR‐NOMA systems (ie, CR‐EH‐NOMA) has also been widely investigated; see References 13‐32 and references therein. In Reference 13, the authors have analyzed the outage and throughput performance of CR‐NOMA systems integrated with EH, where the locations of the users have been modeled using stochastic geometric based approach.…”

This article investigates the outage performance of incremental relaying based energy harvesting non-orthogonal multiple access (IR-EH-NOMA) system. Firstly, we describe the IR-EH-NOMA protocol considering downlink user assisted relaying and power splitting (PS) based EH strategy. We derive analytical expressions for the outage probabilities experienced by the downlink users and the system outage probability of IR-EH-NOMA network, in the presence of imperfect successive interference cancellation (I-SIC). For comparison, we derive the corresponding outage expressions for the conventional cooperative relaying based NOMA network with EH (CR-EH-NOMA network) as well. We provide extensive numerical and Monte-Carlo simulation results to establish the supremacy of IR-EH-NOMA system over CR-EH-NOMA system in terms of the outage performance. We separately derive analytical expressions for (i) the optimal power allocation (OPA) factor at the source and (ii) the optimal power splitting (OPS) factor at the relay that minimizes the asymptotic system outage probability of the considered networks. With the help of numerical and simulation investigations, we establish that the system outage of the considered networks improve significantly when OPA and OPS factors are selected according to the criterion described in the article. The analytical results are validated by extensive simulation studies.
