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

Integrated satellite multiple terrestrial relay network (ISMTRN) is a new network architecture
that combines satellite communication with terrestrial communication. It both utilizes the …

Covert communication is achieved if the transmitter (Alice) sends messages to a legitimate
receiver (Bob) without detection by an attentive warden (Willie). Recently, there has been …

While Gaussian signalling is assumed in many studies on covert communications, its
optimality has not been carefully investigated. In this work, we examine this optimality by …

We present a covert (low probability of detection) communication scheme that exploits the
node multiplicity and channel variations in wireless broadcast networks. The transmitter …

Despite its potential for reducing the detection probability at the warden, the effectiveness of
covert communication in practical situations is often hindered by harsh wireless signal …

We explore the influence of cooperative jamming on covert communication for integrated
satellite–terrestrial relay networks (ISTRN) in this article, where one full-duplex relay is …

Covert communication hides the transmission of a message from a watchful adversary, while
ensuring reliable information decoding at the receiver, providing enhanced security in …

In this paper, we investigate the realization of covert communication in a general radar-
communication cooperation system, which includes integrated sensing and communications …

Covert communications have arisen as an effective communications security measure that
overcomes some of the limitations of cryptography and physical layer security. The main …
