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 paper investigates the impact of partial relay selection scheme (PRSS) on cooperative
underlay cognitive radio (CR) non-orthogonal multiple access (NOMA) networks. Decode …

This paper analyze a new cooperative hybrid underlay–overlay cognitive radio non-
orthogonal multiple access (CHCR-NOMA) system, where a secondary source and a …

In this paper, we consider a non-orthogonal multiple access (NOMA) based underlay
cognitive radio (CR) system consisting of a source, two destinations, and a relay in the …

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 …

In the existing underlay cognitive radio literature, the outage performance of the secondary
network is severely degraded due to the interference from the primary network and the …

we propose an overlay cooperative cognitive radio (CR) non-orthogonal multiple access
(NOMA) network which has channel estimation errors and imperfect successive interference …

In this paper, we study a cooperative non-orthogonal multiple access (NOMA) system
underlying cognitive networks which adapt user relaying and selection combining. The …

In this paper, we employ power-domain non-orthogonal multiple access (NOMA) to
simultaneously transmit signals to both a primary user (PU) and a secondary user (SU) of a …

In this study, the performance of non-orthogonal multiple access systems (NOMA) in relay
assisted cognitive radio (CR) networks is investigated. Mathematical inferences in the …
