Recently, the combination of cognitive radio networks with the nonorthogonal multiple
access (NOMA) approach has emerged as a viable option for not only improving spectrum …

To further improve spectral efficiency, this paper considers a non-orthogonal multiple access
(NOMA)-assisted overlay cognitive radio network consisting of a pair of primary users and a …

This article investigates the performance of reconfigurable intelligent surface assisted two-
way non-orthogonal multiple access (RIS-TW-NOMA) networks, where a pair of users …

This correspondence paper investigates a novel non-orthogonal multiple access (NOMA)
assisted overlay spectrum sharing framework for multiuser cognitive radio networks toward …

Non-orthogonal multiple access (NOMA) has been recently regarded as one of the potential
multiple access candidates for coming fifth generation (5G) communication networks. In this …

Short-packet communication is an important feature of the Internet of Things (IoT). For
allowing massive IoT devices to connect to a network through short packets, this paper …

This paper considers a multiple-input multiple-output (MIMO) non-orthogonal multiple
access (NOMA) cognitive radio (CR) system with an unmanned aerial vehicle relay (UR). In …

In this paper, we investigate the outage behavior of a simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS)-empowered cognitive non-terrestrial …

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 …

With the increasing requirements for efficient utilization of satellite resources, both non-
