This paper proposes a new communication protocol for a cooperative non-orthogonal
multiple access (NOMA) system. In this system, based on users' channel conditions, each …

In this paper, we investigate the effectiveness of an overlay cognitive radio (OCR) coupled
with non-orthogonal multiple access (NOMA) system using a full-duplex (FD) cooperative …

Cooperative non-orthogonal multiple access (CNOMA) is considered as a promising
technique to improve network coverage, reliability and transmission for future wireless …

This paper studies a two-user cooperative non-orthogonal multiple access network with a
novel cooperation scheme, where the source communicates with the near user directly or …

This letter studies the impact of relay selection (RS) on the performance of cooperative non-
orthogonal multiple access (NOMA). In particular, a two-stage RS strategy is proposed, and …

This paper presents a non-orthogonal multiple access (NOMA)-assisted full-duplex (FD)
cooperative spectrum sharing protocol to achieve full-rate at a cell-edge primary user, where …

In this work, a non-orthogonal multiple access (NOMA) based transmission between a
source and two end users is examined over slow Generalized-K distributed (GKD) fading …

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

In this paper, we demonstrate that despite the power constraints on all transmit nodes
caused by the interference temperature limit (ITL) imposed by the primary user, power …

In this letter, a cooperative underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission is investigated. Specifically, exact closed …
