This paper presents the secrecy performance of Cognitive Radio (CR) networks by enabling
non-orthogonal multiple access (NOMA) in downlink. The multiple-input and single output …

This letter studies the secure transmission issue of non-orthogonal multiple access (NOMA)
based cognitive radio networks (CRNs) with imperfect channel state information (CSI) …

This paper investigates the physical layer security of non-orthogonal multiple access
(NOMA) with decode-and-forward (DF) relays in underlay cognitive radio (CR) network …

The Industrial Internet of Things (IIoT) has been recognized as having the potential to offer
substantial benefit to a wide range of industrial sectors. However, the widespread …

The implementation of advanced communication technologies such as nonorthogonal
multiple access technologies (NOMA) and cognitive radio (CR) technology in the Internet of …

In this paper, we propose an innovative framework to improve the physical layer security of
cognitive radio nonorthogonal multiple access (CR-NOMA) networks. Specifically, we …

This paper investigates physical layer security (PLS) in hybrid automatic repeat request
(HARQ)-assisted non-orthogonal multiple access (NOMA) networks, where a security …

This article investigates physical-layer security (PLS) for an energy-harvesting cognitive
network with nonorthogonal multiple access (EHCN-NOMA), where a cognitive base station …

In this paper, an easy analysis framework is developed to evaluate the reliability and
security of the secondary receivers (SU-Rxs) in millimeter wave (mmWave) non-orthogonal …

In this paper, we design a secure transmission scheme in hybrid automatic repeat request
(HARQ) assisted cognitive non-orthogonal multiple access (NOMA) networks, where a …
