The paper presents performance analysis of a multiuser Cooperative Non-Orthogonal
Multiple Access (CNOMA) network that is underlay to a primary network. A selected …

In this paper, we demonstrate that due to large variations in link signal-to-noise-ratios, the
key to good performance in underlay cooperative non-orthogonal multiple access (CNOMA) …

This paper investigates the outage performance of secondary users (SUs) in underlay
cognitive radio–based nonorthogonal multiple access (CR‐NOMA) networks. We consider …

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 …

The non‐orthogonal multiple access (NOMA) technique offers throughput improvement to
meet the demands of the future generation of wireless communication networks. The …

The synergy of nonorthogonal multiple access (NOMA) and cognitive radio (CR) can provide
efficient spectrum utilization for future wireless networks and enable supporting …

The performance of an underlay coordinated direct and relay transmission (CDRT) based
non-orthogonal multiple access (NOMA) network is limited by the random nature of the …

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 …

The primary objective of cognitive radio network is to effectively utilize the unused spectrum
bands. In cognitive radio networks, spectrum sharing between primary and secondary users …

Purpose The purpose of this paper is to present an up-to-date survey on the non-orthogonal
multiple access (NOMA) technique with co-operative strategy, a fast-evolving fifth-generation …
