To meet the network requirements and improve the utilization of system spectrum, a
Cognitive Radio Non-Orthogonal Multiple Access (CR-NOMA) technology is proposed. To …

Abstract Non-Orthogonal Multiple Access (NOMA) is one of the key candidate technologies
for 5G networks. Combined with Cognitive Radio (CR) technology, the CR-NOMA system …

Non-orthogonal multiple access (NOMA) is one of the key candidate technologies of 5G
network. The CR-NOMA system formed by the combination of cognitive radio (CR) …

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 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 paper, we investigate the outage probabilities of secondary destination nodes in
cognitive radio non-orthogonal multiple access (CR-NOMA) systems with imperfect …

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, 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 performance of a multicarrier underlay cognitive radio system is analyzed
considering that the successive interference cancellation (SIC) method is used for detection …

Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are promising for solving
the severe spectral scarcity problem encountered by the next generation of wireless …
