Covert communication aims at achieving a reliable communication while ensuring an
arbitrary small probability of being detected by the adversary. In this paper, we exploit the …

A multi-antenna covert communication system under fading channels is proposed in this
paper, where the existing public communication link is exploited as a cover. With the warden …

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, a covert communication scheme under block-fading channels is proposed
where the relay, apart from forwarding source's information to the destination, also acts as a …

In this paper, we investigate covert communication where the relay and the jammer are
jointly selected. It is demonstrated that the improvement of covert communication …

Covert communication aims to hide the very existence of wireless transmissions which
provides a strong security guarantee for wireless networks. This article considers a dual-hop …

Covert transmission is investigated for a cooperative deception strategy, where a
cooperative jammer (Jammer) tries to attract a multi-antenna adversary (Willie) and degrade …

This article considers a covert wireless communication (CWC) scheme for multi-channel
wireless transmission systems with a full-duplex receiver. Specifically, the transmitter …

In this work, we consider a system of covert communication with the aid of a full-duplex (FD)
receiver to enhance the performance in a more realistic scenario, ie, only the channel …

In this work, the covert communication assisted by a probabilistic jammer is investigated in
the finite blocklength regime, in which the jammer emits jamming signals with a certain …
