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 …

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

As a revolutionary technology, reconfigurable intelligent surface (RIS) has been deemed as
an indispensable part of the 6th generation communications due to its inherent ability to …

In this paper, we analyze the secrecy outage probability (SOP) and the fairness of average
packet transmission time for a non-orthogonal multiple access (NOMA) system which …

In this Letter, the physical layer security for a novel reconfigurable intelligent surface (RIS)‐
assisted non‐orthogonal multiple access (NOMA) system in a multi‐user scenario is …

Reconfigurable intelligence surface (RIS) is regarded as one of the key technologies for the
future wireless communications. Recently, simultaneous transmission and reflection (STAR) …

Although reconfigurable intelligent surface (RIS) can improve the secrecy communication
performance of wireless users, it still faces challenges such as limited coverage and double …

In 5G wireless communication networks, Non-Orthogonal Multiple Access (NOMA) has
attracted much attention in recent years. This paper investigates physical layer security of a …

Non-orthogonal multiple access (NOMA) has come to the fore as a spectrally efficient
technique for fifth-generation networks and beyond. At the same time, NOMA faces severe …

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 …
