“…One can observe that there is the occurrence of some inflection points in the figure . It can be explained that when the value of SNR is in lower range, the EE decreases rapidly. Again, the graph of EE varies towards gradually decreasing as SNR values are towards increasing according to (39) and (51). Thus, the existence of the inflection points in the figure is obvious.…”

“…The reason is that the CRNOMA can achieve a larger throughput and ergodic rate than that of the OMA. The exact theoretical curves of the ergodic rate of two users for the CRNOMA are plotted according to (39) and (51). One can observe that there is the occurrence of some inflection points in the figure . It can be explained that when the value of SNR is in lower range, the EE decreases rapidly.…”

“…The outage probability was then evaluated for the primary and secondary systems. In [39], a hybrid SWIPT protocol combined PS and TS based architecture was investigated for CNOMA downlink transmission. The outage probability and channel capacity were derived and evaluated via simulation results.…”

This study proposes the integration of a cooperative non-orthogonal multiple access (CNOMA) and improved hybrid simultaneous wireless information and power transfer (IHS SWIPT) protocol (termed as CNOMA-IHS) to enhance the spectral efficiency (SE) of a downlink (DL) CNOMA communication system. CNOMA-IHS scheme can enhance the ergodic sum capacity (ESC) and energy efficiency (EE) of DL CNOMA by transferring additional symbols towards the users and energize the relay operation as well without any additional resources (e.g., time slot/frequency/code). The analytical and simulation results indicate that the proposed CNOMA-IHS scheme outperforms other existing SWIPT-based schemes (e.g., CNOMA with hybrid SWIPT, CNOMA with power-splitting SWIPT, wireless-powered CNOMA, CNOMA with time switching SWIPT, and orthogonal multiple access with IHS SWIPT) in terms of the ESC. Moreover, the CNOMA-IHS scheme also enhances EE compared with other conventional TS-SWIPT-based schemes, which is also illustrated by the simulation results. In addition, the proposed CNOMA-IHS scheme with the considered EE optimization technique outplayed the proposed CNOMA-IHS scheme without EE optimization and other existing TS-SWIPT-based schemes in terms of EE.

“…Two different types of CNOMA‐SWIPT protocols can be classified. In the first type, CCU is performed as a relay for the CEU, 19‐22 which is an energy‐constrained node. In the case of the dedicated relay, EH based dedicated relay perform relaying for entire NOMA users 23‐25 .…”

In this study, improved time switching (ITS) simultaneous wireless information and power transfer (SWIPT‐ITS) protocol along with cooperative nonorthogonal multiple access (CNOMA) downlink (DL) transmission are integrated (termed as CNOMA‐SWIPT‐ITS) for DL transmission. CNOMA‐SWIPT‐ITS scheme transfers information to the users and performs energy harvesting (EH) for relay operation from cell center user (CCU) to cell edge user (CEU). Furthermore, the scheme transfers different symbols using the time duration of EH at the CCU and performs cooperative relaying (CCU to CEU) to enhance the channel capacity of the users. The performance of CNOMA‐SWIPT‐ITS scheme is measured in terms of ergodic sum capacity and outage probabilities. Finally, simulation and analytical results demonstrate the superiority of the proposed scheme over conventional CNOMA based SWIPT schemes and typical orthogonal multiple access based ITS SWIPT scheme.
