This paper studies the secure communications of a wireless-powered full-duplex
cooperative non-orthogonal multiple access (CoNOMA) system with a source node, a group …

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

The secrecy outage probability (SOP) performance is investigated for a cooperative non-
orthogonal multiple access system under eavesdropping attack, where a base station …

Reconfigurable intelligent surface (RIS) has the capability of boosting system performance
by manipulating the wireless propagation environment. This paper investigates a downlink …

Both cooperative non‐orthogonal multiple access (NOMA) and physical layer security (PLS)
are promising techniques for future communication systems. This paper investigates the PLS …

In this paper, we investigate the secrecy performance of an Amplify-and-Forward (AF) relay
in a cooperative NOMA system. The AF relay ensures the transmission of the signal in the …

This paper investigates secure cooperative communications in untrusted relay networks,
where a source coordinately communicates with multiple near users and a far user, and the …

Non-orthogonal multiple access (NOMA) has been envisioned as a promising multiple
access technique to improve spectral efficiency and provide massive connectivity in future …
