This paper investigates physical layer security of cooperative NOMA in a severe scenario
where there is no direct link from the source to far destination while the direct link between …

In order to improve the spectrum efficiency and secrecy energy efficiency, in this paper, we
propose a non-orthogonal multiple access (NOMA)-based secure scheme for cognitive radio …

Cooperative communication that integrates cognitive radio and non-orthogonal multiple
access is recognized as an emerging technology for fifth-generation and beyond wireless …

Non-orthogonal multiple access (NOMA) is considered to be one of the best candidates for
future networks due to its ability to serve multiple users using the same resource block …

In this paper, we study the physical layer security (PLS) of a radio frequency energy
harvesting (RF EH) non-orthogonal multiple access (NOMA) relaying network where relay …

In this paper, we evaluate the secrecy performance in terms of secrecy outage probability
(SOP) for Internet of things (IoT) enabled multi-relaying non-orthogonal multiple access …

Non-orthogonal multiple access (NOMA) and wireless energy harvesting are two promising
technologies for improving spectral efficiency and energy efficiency, respectively. In this …
