We consider a covert communication scenario, where a legitimate transmitter (Alice) applies
non-orthogonal multiple access (NOMA) to communicate with a covert user (Bob) and a …

Covert communications hide the transmission of a message from a watchful adversary while
ensuring a certain decoding performance at the receiver. In this paper, a wireless …

We consider that a transmitter covertly communicates with multiple receivers under the help
of a friendly jammer. The messages intended for different receivers are transmitted in …

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

In this letter, we propose a novel energy-efficient covert wireless communication scheme
through probabilistic jamming, where a jammer probabilistically transmits artificial noise …

This paper considers beamforming techniques for covert communication over multiple input
single output (MISO) channels with finite blocklength. We first show that the optimal input …

This paper investigates covert communication in simultaneously transmitting and reflecting
reconfigurable intelligent surface (STAR-RIS) assisted non-orthogonal multiple access …

Covert communications assisted by simultaneously transmitting and reflecting
reconfigurable intelligent surface (STAR-RIS) in non-orthogonal multiple access (NOMA) …

This work investigates the phase gain of intelligent reflecting surface (IRS) covert
communication over complex-valued additive white Gaussian noise (AWGN) channels. The …

This letter studies a wireless covert communication system, where a jammer generating
intermittent artificial noise (AN) is employed to confuse the warden. The transmission …
