We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

This paper analyzes the secrecy capacity of a cooperative relaying system using non-
orthogonal multiple access (NOMA). A new cooperative NOMA scheme is proposed, where …

Non-orthogonal multiple access (NOMA) is an important technology for the forthcoming 5 G
and beyond. However, its privacy often suffers from adversarial eavesdropping, especially …

In this paper, we investigate an artificial-noise (AN) aided secure transmission for non-
orthogonal multiple access (NOMA) full-duplex (FD) relay network. We propose a novel joint …

This paper studies the impacts of antenna selection algorithms in decode‐and‐forward (DF)
cooperative nonorthogonal multiple access (NOMA) networks, where the secure information …

This paper investigates the security performance of two relay selection schemes for
cooperative non-orthogonal multiple access (NOMA) systems, where K randomly distributed …

This letter investigates a jammer-aided cooperative non-orthogonal multiple access (NOMA)
system, where one relay is used to deliver information and other relays are acted as …

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

In this letter, we consider a non-orthogonal multiple access (NOMA) network with a half-
duplex (HD) decode-and-forward (DF) relay to improve physical layer security (PLS) of two …

This paper analyzes the secrecy attributes of a full-duplex relay (FDR) non-orthogonal
multiple access (NOMA) system, where the best relay is chosen from a set of numerous …
