“…A fixedantenna assignment and an adaptive-antenna assignment are proposed to improve the system throughput. The authors in [5]- [12] consider two-phase SWIPT systems with SER at the relay node. With T representing the total block duration, the first phase of the duration T /2 is used by the source for sending information to the relay.…”

“…The SI signal at the relay is in fact beneficial since the relay not only harvests energy from the source, but also recycles energy from the self-interfering link. In all these time-switching-based SWIPT relaying systems [5]- [12], the information signal is transmitted and received in different phases, so that the SIC is not required to eliminate SI. However, this also means that the relay cannot receive information from the source and transmit information to the destination at the same time, thus limiting the system throughput.…”

This paper proposes a Polarization-Enabled Digital Self-Interference Cancellation (PDC)based Full-Duplex (FD) network with an energy-harvesting-enabled source and a Self-Energy Recycling (SER)-enabled relay. The fixed power supply at the relay is only used in the first phase to broadcast energy signals to the source. During this process, the receive antenna of the relay also receives the energy signals, allowing the relay to recycle its own energy. In the remaining phase, the recycled power is used at the relay to forward signals from the source to the destination, using the PDC-based full-duplex technique. An in-depth analysis and comparison of the throughput of the proposed system with that of the non-recycling counterpart are presented. The power saving and throughput improvement capabilities of the SER enabled system is researched. In particular, the consumed power in the proposed system can be reduced by up to 80% to achieve the same throughput compared to the non-recycling system for a small-to-medium distance range between the relay and the destination. Alternatively, the proposed FD-SER system can boost the system throughput by 1.61 times the non-recycling counterpart with the same power consumption.INDEX TERMS Self-energy recycling, full-duplex, self-interference, RF-powered relay channel.

“…The combination of wireless-powered FD technology and NOMA improves the SE of the system and provides energy supply to the energy-constrained nodes to increase their working time, which deserves significant attention and investigation. In [4], Yang et al considered a decode-and-forward (DF) FD wireless relay network with self-energy recycling and analyzed the outage probability performance of this system. In [5], Liu et al proposed a new cooperative NOMA scheme with simultaneous wireless information and power transfer (SWIPT), where the user close to the transmitter worked as a wireless-powered relay to help the far user.…”

Non-orthogonal multiple access (NOMA) and wireless energy harvesting are two promising technologies for improving spectral efficiency and energy efficiency, respectively. In this paper, we study the physical layer security of a wireless-powered full-duplex (FD) relay-aided cooperative NOMA system. In particular, the source is wiretapped by an eavesdropper, and the FD relay assists the transmission from the source to a near user and a far user with self-energy recycling. To enhance the security performance of the system, we propose an artificial noise (AN)-aided cooperative transmission scheme, in which the relay emits a jamming signal to confuse the eavesdropper while receiving the signal from the source. For the proposed scheme, the ergodic secrecy sum rate (ESSR) is derived to characterize the secrecy performance and a lower bound of ESSR is obtained. Finally, numerical results verify the accuracy of the theoretical analysis of the proposed AN-aided secure transmission scheme. The superiority of the proposed scheme is also demonstrated since this scheme can achieve better secrecy performance, compared to the conventional cooperative NOMA scheme.
