“…It is also noted that there is one half spectral efficiency penalty for relaying in (11), whereas there is no spectral efficiency penalty in (12) as the source transmits an independent data symbol to the destination directly for a given time slot when ݃ ௌ > ݃ ௌோ . Then, using (11) and (12), the achievable average rate of the O-NOMA is obtained as…”

In this paper, we propose the opportunistic non-orthogonal multiple access (NOMA)-based cooperative relaying system (CRS) with channel state information (CSI) available at the source, where CSI for the sourceto-destination and source-to-relay links is used for opportunistic transmission. Using the CSI, for opportunistic transmission, the source instantaneously chooses between the direct transmission and the cooperative NOMA transmission. We provide an asymptotic expression for the average achievable rate of the opportunistic NOMA-based CRS under Rayleigh fading channels. We verify the asymptotic analysis through Monte Carlo simulations, and compare the average achievable rates of the opportunistic NOMA-based CRS and the conventional one for various channel powers and power allocation coefficients used for NOMA.

The CNOMA-SWIPT protocols presented in other works [18][19][20]23 employ PS receiver architecture, whereas the works of Do et al 21 and Kader et al 22 employ PS/TS receiver architecture. Outage probability (OP) of a CNOMA-SWIPT downlink transmission protocol was investigated in the work of Do et al, 21 where a near or cell-center user acts as a TS/PS-based EH relay for the cell-edge or far user.…”

To meet with both the energy and spectral efficiency, cooperative non‐orthogonal multiple access (NOMA) (termed as CNOMA) and simultaneous wireless information and power transfer (SWIPT) are integrated in this paper. Two different protocols such as CNOMA‐SWIPT‐PS and CNOMA‐SWIPT‐TS are proposed, by employing power‐splitting (PS) and time‐switching (TS) energy harvesting (EH) techniques, respectively. In the proposed protocols, a base station (BS) directly communicates with a NOMA near user, whereas the communication with a NOMA far user is performed with the assistance of an energy‐constrained relay node. The relay node harvests energy from the transmitted signal by the BS, employing PS or TS EH technique. We investigate ergodic sum capacity and outage probability of the proposed protocols along with analytical derivations over Nakagami‐m fading channels. Finally, the effectiveness of the proposed schemes over existing strategy and conventional multiple access is demonstrated through analysis and simulation.
