Non-orthogonal multiple access (NOMA) and full duplex (FD) relaying are two promising techniques to enhance the spectral efficiency of the fifth generation (5G) wireless networks. Simultaneous wireless information and power transfer (SWIPT) technique has recently emerged as an effective solution to improve the energy efficiency of wireless networks. This paper investigates outage and throughput performance of SWIPT enabled FD cooperative NOMA network under power splitting relaying (PSR) protocol, i.e., SWIPT enabled FD-PSR-NOMA network. We assume a single cell network consisting of a base station (BS) and two pre-paired users, i.e., a near user and a far user, where the near user acts as FD relay to assist the BS for information delivery to the far user, and power splitting (PS) technique is used at the relay for energy harvesting (EH). We derive analytical expressions for the outage probabilities experienced by the downlink users, system outage probability and delay limited system throughput under imperfect successive interference cancellation (i-SIC). We also derive analytical expressions for outage probabilities and throughput of SWIPT enabled half duplex (HD) cooperative NOMA network under PSR, i.e., SWIPT enabled HD-PSR-NOMA network. The optimal power allocation (OPA) factor at the BS and optimal power splitting (OPS) factor at the relay that independently minimizes the asymptotic system outage probabilities of SWIPT enabled FD/HD-PSR-NOMA networks are determined. Further, we explore the jointly optimal power allocation and power splitting factor that minimize the system outage probability. Furthermore, we derive analytical expression for the OPS factor that maximizes the asymptotic system throughput. We provide extensive numerical and simulation results to establish that system outage and throughput improve significantly under the proposed schemes.

非正交多址（NOMA）和全双工（FD）中继是提高第五代（5G）无线网络频谱效率的两种有前途的技术。同步无线信息和功率传输（SWIPT）技术近来已成为提高无线网络能效的有效解决方案。本文研究了功率分配中继（PSR）协议下启用SWIPT的FD协作NOMA网络（即启用SWIPT的FD-PSR-NOMA网络）的中断和吞吐量性能。我们假设一个由基站（BS）和两个预配对用户组成的单小区网络，即，一个近距离用户和一个远距离用户，其中近距离用户充当FD中继以协助BS将信息传递给远距离用户，并且在继电器上使用功率分配（PS）技术进行能量收集（EH）。我们得出了不完善的连续干扰消除（i-SIC）下下行用户遇到的中断概率，系统中断概率和延迟受限系统吞吐量的解析表达式。我们还导出了在PSR下启用SWIPT的半双工（HD）协作NOMA网络（即启用SWIPT的HD-PSR-NOMA网络）的中断概率和吞吐量的解析表达式。确定了在BS处的最佳功率分配（OPA）因子和在继电器处的最佳功率分配（OPS）因子，这些因子独立地最小化了启用SWIPT的FD / HD-PSR-NOMA网络的渐近系统中断概率。进一步，我们探索了联合最优的功率分配和功率分配因子，以最小化系统中断的可能性。此外，我们导出了OPS因子的解析表达式，该表达式使渐近系统的吞吐量最大化。我们提供了广泛的数值和仿真结果，以证明在建议的方案下，系统中断和吞吐量可以显着提高。
