In this correspondence, we investigate the reliability and the security of the ambient
backscatter (AmBC) non-orthogonal multiple access (NOMA) systems, where the source …

Enhancing security level against potential internal eavesdroppers in Non-Orthogonal
Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel …

The application of successive interference cancellation (SIC) introduces critical security risks
to cooperative non-orthogonal multiple access (NOMA) systems in the presence of …

One of the main characteristics of the power-domain non-orthogonal multiple access
(NOMA) technique is the possibility of users to decode the messages of the other paired …

The secrecy outage probability (SOP) performance is investigated for a cooperative non-

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 …

In this paper, we propose a novel beamforming design to enhance physical layer security of
a non-orthogonal multiple access (NOMA) system with the aid of artificial noise (AN). The …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
