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

In this letter, we investigate covert communications in an active reconfigure intelligent
surface (RIS) aided multiple-input single-output non-orthogonal multiple access system. To …

In this article, we investigate covert communication in simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS)-assisted networks with rate-splitting …

With the development of the sixth-generation wireless communication technology, the
difficulty of covert communication in the satellite communications system (SCS) is further …

This letter considers the spatial correlation between the channels related to the warder and
receiver in an intelligent reflecting surface (IRS)-aided covert communication system. Based …

Covert wireless communication intends to prevent hostile surveillance but is threatened by
the powerful multi-antenna detection technique. In this paper, we investigate finite …

This letter investigates covert communication in an intelligent reflecting surface (IRS)-
assisted system. We propose a novel algorithm that jointly optimizes the transmission …

This letter investigates the multi-input multi-output (MIMO) covert communication aided by
intelligent reflecting surface (IRS) against a multi-antenna warden. We establish a design …

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 …
