Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are envisioned as
promising solutions to achieve high spectral efficiency for future wireless networks. This …

In this article, we investigate the performance of spectrum sharing inunderlay cognitive radio
(CR)-inspired nonorthogonal multiple access (NOMA) systems, at which a primary …

This study considers the outage and throughput performance of downlink in the secondary
network of cognitive radio assisted non-orthogonal multiple access (NOMA) systems. Both …

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 …

This correspondence paper considers a dual-hop underlay cognitive radio nonorthogonal
multiple access (NOMA) network. The end-to-end outage probability (OP) is evaluated as …

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

To further improve spectral efficiency, this paper considers a non-orthogonal multiple access
(NOMA)-assisted overlay cognitive radio network consisting of a pair of primary users and a …

In this paper, we investigate the performance of a secondary network in a cognitive radio
network employing a non-orthogonal multiple access (NOMA) scheme to form a CR-NOMA …

In this paper, the power allocation of Non-orthogonal multiple access (NOMA) for secondary
users in underlay cognitive radio is studied. In underlay cognitive radio networks, the …

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 …
