We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

This article studies the reliable and secure communications for a wireless-powered non-
orthogonal multiple access (NOMA) system in the presence of multiple eavesdroppers. A …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

Considering the diversified communication requirements in the Internet-of-Things (IoT)
networks, this article proposes a nonorthogonal multiple access (NOMA) scheme which …

We investigate physical layer security of an uplink NOMA system consisting of one base
station, multiple users and one eavesdropper. During each uplink transmission, two users …

In order to improve the spectrum efficiency and secrecy energy efficiency, in this paper, we
propose a non-orthogonal multiple access (NOMA)-based secure scheme for cognitive radio …

Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is
becoming a prospective technology in realizing extremely low power transmission and …

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

Combination of unmanned aerial vehicle (UAV) and non-orthogonal multiple access
(NOMA) is deemed as an promising solution to achieving massive connectivity in future …

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 …
