“…However, the disadvantage of the methods proposed in [13], [14] is that the practical EH circuits cannot forward the received information and simultaneously extract power from the same received signal [17]. In [15], the authors consider a FD relaying system with multiple transmit and receive antennas at the relay. The proposed antenna allocation scheme can allot the antennas at both transmit and receive ends for either SER or information relaying.…”

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 numerous advantages of RIS have motivated great interest in analysing RIS reflection beamforming designs in diverse RIS-aided wireless systems [7]- [9]. On a similar note, another technological advancement called full-duplex (FD) communication has the potential to improve the spectral efficiency of the system by transmitting and receiving the signal simultaneously using the same resources [10], [11]. Therefore, the integration of the RIS into FD communication systems has been well motivated by researchers [12]- [14] in order to achieve low power reliable RIS-assisted transmission with an efficient use of the available resources.…”

With the advancement of wireless communication technologies, reconfigurable intelligent surfaces (RISs) have recently paved the way to augmenting the performance of wireless networks with the aid of multiple reflecting surfaces by efficiently attuning the signal reflection through a large number of low-cost passive elements. In this paper, we consider an RIS-aided fullduplex (FD) communication network consisting of a FD access point (AP) that communicates with an uplink and a downlink user simultaneously with the aid of an RIS as well as through the direct link between the AP and users. To evaluate the system performance under infinite blocklength (IBL) and finite blocklength (FBL) codes, we derive the analytical expressions for the outage probability and throughput in case of IBL, and for block-error rate (BLER) and goodput in the case of FBL, for both uplink and downlink transmission. Furthermore, the expressions for the maximum achievable rate under FBL and IBL transmission are derived. Next, we also extend the analysis of the single-user framework to a more practical scenario with multiple users utilizing non-orthogonal multiple access (NOMA) and derive analytical expressions for the outage probability and BLER at each downlink user and at the AP. The accuracy of the derived expressions is validated via simulation results, and insights are provided regarding the impact of the number of reflecting elements and imperfect channel state information (CSI) on the performance of the considered system. Finally, from the comparative analysis, it is shown that the RIS-aided system outperforms the system without RIS in both IBL and FBL scenarios, providing remarkable improvement in the outage probability and BLER.
