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

This work examines the performance gain achieved by deploying an intelligent reflecting
surface (IRS) in covert communications. To this end, we formulate the joint design of the …

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

Reconfigurable intelligent surfaces have emerged as a promising technology for future
wireless networks. Given that a large number of reflecting elements is typically used and that …

While sixth-generation (6G) wireless systems are expected to bring about an explosion of
accessible user information and novel technologies, along with new threats to terrestrial and …

This article investigates the intelligent reflecting surface (IRS)-aided multi-antenna covert
communications. In particular, with the help of an IRS, a favorable communication …
