This paper proposes a novel non-orthogonal multiple access (NOMA)-based cooperative
transmission scheme for a spectrum-sharing cognitive radio network (CRN), whereby a …

This paper investigates the opportunistic sharing of relay for the proposed Non-Orthogonal
Multiple Access (NOMA) assisted Cognitive Radio Networks (CRNs). The proposed scheme …

The combination of non-orthogonal multiple access (NOMA) and cooperative
communications can be a suitable solution for fifth generation (5G) and beyond 5G (B5G) …

In uplink non-orthogonal multiple access (NOMA) channels, the existing cooperative
successive interference cancellation (SIC) and power control (PC) schemes lack the …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient multiple access
technique for the fifth generation (5G) wireless networks. In this paper, we propose a …

This paper studies the application of non-orthogonal multiple access (NOMA) to a
cooperative multicast system (termed CM-NOMA). In particular, the multicast subscribers are …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
