This paper considers a cognitive radio inspired uplink communication scenario, where one
primary user is allocated with one dedicated resource block, while M secondary users …

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

Nowadays, 5G puts forward a number of candidate multiple access technologies, among
which the non-orthogonal multiple access (NOMA) is attracting more and more attention …

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

In this paper, the outage performance of a cognitive radio network under the joint constraint
of multiple primary users (PUs) and a secondary user (SU) is investigated. More specifically …

The demands for high spectral efficiency and massive connections led the researchers to
investigate new multiple access techniques for the future wireless networks. Non-Orthogonal …

In Cognitive Radio Non-Orthogonal Multiple Access (CR-NOMA), hybrid successive
interference cancellation (SIC) was proposed to improve the probability for a secondary user …

In underlay cognitive radio networks, imperfect channel knowledge will have an adverse
effect on the performance of both the primary users (PU) and the secondary users (SU) …

This article studies the interweave cognitive network with non-orthogonal multiple access
(NOMA) principle under the appearance of one eavesdropper. The best relay selection …

This paper studies the secondary network relying relay selection to transmit signal from the
secondary source (base station) to two destinations. Especially, two destinations are …
