In this paper, we develop a non-orthogonal multiple access (NOMA)-based two-way relay
network with secrecy considerations, in which two users wish to exchange their NOMA …

In a downlink non-orthogonal multiple access (NOMA) system, the reliable transmission of
cell-edge users cannot be guaranteed due to severe channel fading. On the other hand, the …

We propose a novel non-orthogonal multiple access (NOMA)-inspired jamming and relaying
scheme to enhance the physical layer security of untrusted relay networks. Particularly …

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 …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …

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 investigates the secrecy outage performance for a large-scale downlink system
with full-duplex (FD) non-orthogonal multiple access (NOMA) transmission aided by artificial …

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 …

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

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and …
