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

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 …

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

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 …

In the existing underlay cognitive radio literature, the outage performance of the secondary
network is severely degraded due to the interference from the primary network and the …

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 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 …

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 letter, a cooperative non-orthogonal multiple access system with imperfect successive
interference cancellation is investigated in an underlay cognitive radio network. Considering …
