Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

It has been predicted that by the year 2030, 5G and beyond 5G (B5G) networks are
expected to provide hundreds of trillions of gigabytes of data for various emerging …

Cognitive radio (CR) and non-orthogonal multiple access (NOMA) have been deemed two
promising technologies due to their potential to achieve high spectral efficiency and massive …

Considering reconfigurable intelligent surfaces (RISs), we study a multi-cluster multiple-
input-single-output (MISO) non-orthogonal multiple access (NOMA) downlink …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

Owing to its distinctive merits, non-orthogonal multiple access (NOMA) techniques have
been utilized in unmanned aerial vehicle (UAV) enabled wireless base stations to provide …

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 develop a non-orthogonal multiple access (NOMA)-based two-way relay
network with secrecy considerations, in which two users wish to exchange their NOMA …

In this paper, we consider max-min fairness for a downlink two-user multi-input single-output
(MISO) system with imperfect channel state information available at transmitter (CSIT) taking …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …
