In the past as well as present wireless communication systems, the wireless propagation
environment is regarded as an uncontrollable black box that impairs the received signal …

Recent intensive and extensive development of the fifth-generation (5G) of cellular networks
has led to their deployment throughout much of the world. As part of this implementation …

We consider an intelligent reflecting surface (IRS) wireless-powered NOMA Internet-of-
Things (IoT) network, where multiple NOMA IoT devices can communicate with access point …

The novel concept of simultaneously transmitting and reflecting reconfigurable intelligent
surface (STAR-RIS) is investigated, where incident signals can be transmitted and reflected …

Reconfigurable intelligent surfaces (RISs) and nonorthogonal multiple access (NOMA) have
been recognized as key enabling techniques for the envisioned sixth generation (6G) of …

In this paper, we investigate covert communication in an intelligent reflecting surface (IRS)-
assisted non-orthogonal multiple access (NOMA) system, where a legitimate transmitter …

Abstract Power Domain Non-Orthogonal Multiple Access (PD-NOMA) is a potential
technology for the next generation of cellular networks. Compared to classical orthogonal …

This paper proposes a novel network framework of intelligent reflecting surface (IRS)-
