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 design of power allocation is studied to maximize the spectral efficiency of
a non-orthogonal multiple access-based two-way full-duplex relaying system. Due to the …

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

This study investigates a two-way relaying non-orthogonal multiple access (TWR-NOMA)
enabled Internet-of-Things (IoT) network, in which two NOMA users communicate via an IoT …

In this study, the authors present and investigate a novel cooperative relaying scheme for
cognitive radio networks (CRNs), which is based on non‐orthogonal multiple access …

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 …

To improve the throughput and the outage probability of the Cognitive Radio (CR) inspired
system, a novel Non-Orthogonal Multiple Access (NOMA) can be deployed to adapt multiple …
