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 non‐orthogonal multiple access (NOMA) systems, it may not be advisable to send the
superimposed signal of all users to individual users with retransmission requirements during …

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

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

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

In this paper, we study the application of the non orthogonal multiple access (NOMA) and
orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …

This paper is considered as an application of a centralized control non orthogonal multiple
access (NOMA) based cognitive radio network. Here, a base station (BS) sends …

In this paper, we study a power domain non-orthogonal multiple access (NOMA) scheme for
cognitive cooperative radio networks (CCRNs). In the proposed scheme, a secondary …
