This paper does the study on the performance of the physical layer secrecy of
nonorthogonal multiple access (NOMA) in downlink cooperative. The given system includes …

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 …

In this letter, we investigate the secrecy outage performance of a cooperative non-
orthogonal multiple access (NOMA) network, where a base station (BS) communicates with …

Non-orthogonal multiple access (NOMA) technique can potentially increase spectral
efficiency and improve the network capacity of wireless networks. Ergodic secrecy capacity …

In this paper, we investigate the physical layer security of a non-orthogonal multiple access
(NOMA) based downlink hybrid satellite-terrestrial relay network where the satellite …

This letter considers a trusted decode-and-forward relay-assisted two-user non-orthogonal
multiple access (NOMA) communication system, and tackles the secure rate maximization …

In this paper, we address the physical-layer security of two-way (bi-directional)
transmissions of two terminals with the help of multiple relay nodes in the presence of an …

In this paper, we propose a novel antenna selection scheme to enhance the secrecy
performance in a relay-aided non-orthogonal multiple access (NOMA) network against an …

We investigate physical layer security of a downlink cooperative non-orthogonal multiple
access system with an untrusted relay. A friendly jammer (FJ) is employed in order to …

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 …
