“…In recent years, the combination of CR-NOMA and the wireless power technique has attracted widespread attention. The authors in [19] illustrated a full duplex DF cooperative NOMA network, where the relay can recycle its energy from the self-loop interference channel based on the SWIPT technique. The results illustrated that energy harvesting in cooperative NOMA can improve the outage performance significantly.…”

Improving spectral efficiency under a certain energy limitation is an important design metric for future wireless communications as a response to the growing transmission demand of wireless devices. In order to improve spectral efficiency for communication systems without increasing energy consumption, this paper considers a non-orthogonal multiple access (NOMA)–based cognitive radio network, with the assistance of a wireless-powered relay station (RS), and then analyzes the system outage performance under amplified-and-forward (AF) and decoded-and-forward (DF) cooperative transmission modes. Specifically, the base station (BS) has the opportunity to cooperate by transmitting information through the RS, depending on whether the RS can harvest sufficient RF energy for cooperative transmission. That is to say, when the energy stored by the RS is sufficient for cooperative transmission, the RS will assist the BS to forward information; otherwise, the BS will send information through direct links, while the RS converts the radio frequency (RF) signals sent by the BS into energy for future transmission. Moreover, the transmission power required by the RS for cooperative transmission is usually relatively large, while the amount of harvested energy by the RS in a transmission slot is usually low, so it takes several consecutive time slots to accumulate enough transmission energy. To this end, we utilize a discrete-time Markov chain to describe the processes of charging and discharging of the RS. Subsequently, we derive the closed-form outage probabilities of both the primary and secondary systems for the considered system in AF and DF modes through mathematical analysis, and verify the accuracy of the analyses through Monte Carlo simulation. The simulation results show that the two proposed cooperative transmission schemes with AF and DF relaying techniques outperform both direct transmission and other similar schemes in both the primary and secondary system, while the DF scheme can provide better performance than the AF scheme within the range of setting values.

“…In [10], the two‐hop DF relaying system with an energy‐constrained source node was considered, and the corresponding high SNR approximations of the average symbol error rate were obtained. In [11], an energy harvesting aided full duplex decode and forward cooperative NOMA (CNOMA) network was considered. The closed‐form expression for the exact outage performance of both near‐user and far‐user in the Nakagami‐m fading channel were derived.…”

In this article, a relaying network with simultaneous wireless information and power transfer (SWIPT) is considered, where the relaying nodes are energy‐constrained. The relaying nodes rely on energy harvesting (EH) technique for energy supply and they use different directive transmitters for information transmission and energy transfer, respectively, to enhance the SWIPT relaying performance. A novel discrete‐time‐switch and power‐split (DTS‐PS) based energy harvesting mixture transmission (EH‐MT) protocol for each EH decode and forwarding (DF) relaying node is proposed. The expressions for the average information rate and the energy transfer power are derived analytically and verified by simulations. An optimization function is formulated, and the optimal parameters are obtained analytically and verified by simulation.
