In this letter, we investigate covert communications with finite blocklength under the channel
inversion power control (CIPC) scheme, where a transmitter is allowed to communicate with …

In this work, we adopt channel inversion power control (CIPC) to achieve covert
communications aided by a full-duplex receiver. Specifically, the transmitter varies the power …

Covert communications enable a transmitter to send information reliably in the presence of
an adversary, who looks to detect whether the transmission took place or not. We consider …

Covert communication is to achieve a reliable transmission from a transmitter to a receiver
while guaranteeing an arbitrarily small probability of this transmission being detected by a …

This work, for the first time, tackles channel estimation design with pilots in the context of
covert wireless communication. We consider Rayleigh fading for the communication channel …

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

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 …

This paper investigates the achievable message transmission rate of covert communication
over slow fading channels where the channel coefficient remains unchanged over a finite …

In a majority of research on covert communications, knowledge about channel state
information (CSI) of main channel and/or warden channel is assumed to be known or …

A covert communication system under block fading channels is considered, where users
experience uncertainty about their channel knowledge. The transmitter seeks to hide the …
