In this paper, we investigate two-way decode-and-forward scheme with non-orthogonal
multiple access (NOMA) in underlay cognitive networks to increase efficiency of spectrum …

Non-orthogonal multiple access (NOMA) is recognized as a competing technology to
address the challenges of 5th generation (5G) future wireless networks. In this context …

In this paper, we investigate a cognitive non-orthogonal multiple access (NOMA) network
scenario by adopting an amplify-and-forward (AF) relaying method. The end-to-end outage …

In this paper, we analyze the performance of an underlay downlink non-orthogonal multiple
access (NOMA) network with multiple near and far-users. Different from cognitive radio (CR) …

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 …

In this paper, we study a power domain non-orthogonal multiple access (NOMA) scheme for
cognitive cooperative radio networks (CCRNs). In the proposed scheme, a secondary …

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 …

This study considers an underlay cognitive radio (CR) system, where the secondary network
employs cooperative non‐orthogonal multiple access (NOMA) to transfer information for …

In this paper, we investigate the performance of full duplex relay (FDR) assisted cognitive
radio (CR) network employing Non-orthogonal multiple access (NOMA) scheme. In this …

This paper investigates the joint relay and antenna selection strategy for amplify-and-
forward (AF) cognitive radio-inspired non-orthogonal multiple access (CR-NOMA) systems …
