The concept of simultaneously transmitting and reflecting reconfigurable intelligent surfaces
(STAR-RISs) has been proposed to overcome the limitation of conventional reflecting-only …

In this paper, we propose a novel antenna selection scheme to enhance the secrecy
performance in a relay-aided non-orthogonal multiple access (NOMA) network against an …

We introduce the cooperative full-duplex relaying to a downlink non-orthogonal multiple
access (NOMA) system and analyze the secrecy performance of each NOMA user. In …

In this paper, an Internet-of-Things (IoT) system containing a relay selection is studied as
employing an emerging multiple access scheme, namely non-orthogonal multiple access …

In this paper, a novel approach is introduced to study the achievable delay-guaranteed
secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study …

The objective of this paper is to propose techniques for enhancing the physical layer security
(PLS) performance of half-duplex cooperative non-orthogonal multiple access (HD-CNOMA) …

This paper investigates the impact of physical layer secrecy on the performance of a unified
non-orthogonal multiple access (NOMA) framework, where both external and internal …

In this work, we consider the use of a simultaneously transmitting and reflecting
