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, we propose a covert communication scheme where the transmitter attempts to
hide its transmission to a full-duplex receiver, from a warden that is to detect this covert …

Covert communication can prevent adversary from knowing the existence of the
transmissions while guaranteeing the security in wireless communications. In this paper …

Covert communication can hide the information transmission process from the warden to
prevent adversarial eavesdropping. However, it becomes challenging when the warden can …

Covert communication achieved by using the full-duplex (FD) receiver has wide
applications. Specifically, the FD receiver can emit artificial noise to prevent the signal of …

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 …

Covert communication can be traced back to secret information transmission technology. It
aims to ensure that the transmitters and receivers establish reliable communication with a …

In this letter, we propose a random sub-channel selection covert transmission (RSCT)
scheme in multi-channel systems to enhance the covertness of communication. We derive …

Due to the open accessibility of wireless networks with severe privacy risks, covert
communication has gained increasing attention, where the effective range is limited by the …
