To accommodate the stringent requirements of enhanced coverage quality and improved
spectral efficiency, simultaneous transmitting and reflecting reconfigurable intelligent surface …

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 paper, we investigate the physical layer security of wireless-powered cooperative non-
orthogonal multiple access (NOMA) systems with an energy harvesting (EH) friendly …

In this article, we study the physical-layer security (PHY-security) improvement method for a
downlink nonorthogonal multiple access (NOMA) system in the presence of an active …

This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the …

In this paper, we propose a two-way relaying scheme using non-orthogonal multiple access
(NOMA) technology. In this scheme, two sources transmit packets with each other under the …

This letter studies the secure transmission issue of non-orthogonal multiple access (NOMA)
based cognitive radio networks (CRNs) with imperfect channel state information (CSI) …

Active reconfigurable intelligent surface (RIS) is deemed a prospective candidate to
compensate the double fading attenuation caused by the passive RIS, where each element …

In this paper, we examine the physical layer security of a cooperative relay network where
two source-destination pairs communicate through a decode-and-forward (DF) relay in the …

A new paradigm of uplink non-orthogonal multiple access along with multiple
eavesdroppers to achieve secrecy transmission is studied in this paper. We investigate the …
