In this paper, we investigate a secure cognitive radio network (CRN), which deploys non-
orthogonal multiple access (NOMA) to deliver a mixed multicast and unicast traffic to the …

Cognitive radio (CR) and non-orthogonal multiple access (NOMA) can be regarded as two
promising technologies which bestows with tremendous possible solutions for the next …

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 physical layer security (PLS) in nonorthogonal multiple access-
enabled (NOMA-enabled) cognitive radio networks (CRNs). Considering an existing …

An underlay cognitive radio network (CRN) with non-orthogonal multiple access (NOMA) is
a promising multiple access scheme to solve the problem of scarce spectrum. This novel …

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 the physical layer security of a cognitive radio (CR) non-orthogonal
multiple-access (NOMA) network supported by an intelligent reflecting surface (IRS). In a CR …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

Security performance and the impact of imperfect channel state information (CSI) in underlay
cooperative cognitive networks (UCCN) is investigated in this paper. In the proposed …

In this article, physical layer security is investigated in a non-orthogonal multiple access
(NOMA) network with unmanned aerial vehicle (UAV) relay in the context of underlay …
