Differentsystemmodels utilizing nonorthogonal multiple access (NOMA) have been
successfully studied to meet the growing capacity demands of the Internet of Things IoT) …

In this paper, we consider the secrecy outage probability (SOP) of a cooperative non-
orthogonal multiple access (NOMA) vehicular communication (VC) system, where the relay …

This paper studies the physical layer security for a cooperative non-orthogonal multiple
access system with energy harvesting (EH) and full-duplex (FD) relaying. In particular, the …

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 …

In this paper, we investigate cooperative secure transmission in non-orthogonal multiple
access (NOMA) networks where a source (Alice) intends to transmit confidential messages …

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 letter, we investigate the ergodic secrecy sum rate of a two-way relay NOMA system.
In particular, by considering decode-and-forward signal processing at the relay and …

Full-duplex (FD) relay systems including a transmit antenna selection and a non-orthogonal
multiple access (NOMA) methods are analyzed under presence of multiple eavesdroppers …

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 …

A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior information about the messages of other users. The …
