This paper investigates the outage performance of secondary users (SUs) in underlay
cognitive radio–based nonorthogonal multiple access (CR‐NOMA) networks. We consider …

This study considers an underlay cognitive radio (CR) system, where the secondary network
employs cooperative non‐orthogonal multiple access (NOMA) to transfer information for …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

A novel non-orthogonal multiple access (NOMA) scheme is proposed to improve the
throughput and the outage probability of the cognitive radio (CR) inspired system which has …

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

Non-orthogonal multiple access (NOMA) has been recently regarded as one of the potential
multiple access candidates for coming fifth generation (5G) communication networks. In this …

In this study, a cooperative non‐orthogonal multiple access (NOMA) scheme is investigated
in an underlay cognitive radio network. With this aim, a number of secondary users are …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

In this study, the authors present and investigate a novel cooperative relaying scheme for
cognitive radio networks (CRNs), which is based on non‐orthogonal multiple access …
