In this paper, we propose a downlink cognitive non-orthogonal multiple access (NOMA)
network, where the secondary users (SUs) operate in underlay mode. In the network …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

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 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 …

This paper analyzes the outage performance of cognitive-inspired non-orthogonal multiple
access (NOMA) network under imperfect successive interference cancellation (SIC), co …

The performance of the cognitive non-orthogonal multiple access (NOMA) systems with
random locations is examined in the present paper. More precisely, the positions of the …

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 …

Non orthogonal multiple access (NOMA) in cognitive radio (CR) network has been
recognized as potential solution to support the simultaneous transmission of both primary …

In this article, the performance of cognitive radio system benefits from non-orthogonal
multiple access (NOMA) scheme. We then examine system metrics to adjust its quality of …

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 …
