Information security has always been a critical issue in wireless networks. Apart from other
secure techniques, covert communication emerges as a potential solution to security for …

Recent work has established that when transmitter Alice wishes to communicate reliably to
recipient Bob without detection by warden Willie, with additive white Gaussian noise …

We consider the situation in which a transmitter attempts to communicate reliably over a
discrete memoryless channel, while simultaneously ensuring covertness (low probability of …

Extensive research attentions have been devoted to studying cooperative cognitive radio
networks (CCRNs), where secondary users (SU) providing cooperative transmissions can …

This article investigates the covert performance of an unmanned aerial vehicle (UAV)
jammer-assisted cognitive radio (CR) network. In particular, the covert transmission of …

If the warden Willie attempting to detect the transmission knows the statistics of his receiver
noise, Alice can transmit no more than covert bits reliably to Bob in channel uses of an …

This paper investigates the fundamental covert rate performance in a wireless relaying
system consisting of a source-destination pair, a full-duplex (FD) relay and a warden, where …

This article investigates the covertness and secrecy of wireless communications in an
untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base …

We consider a scenario in which two legitimate transmitters attempt to communicate with a
legitimate receiver over a discrete memoryless Multiple-Access Channel (MAC), while …

This paper investigates the covert communication of cooperative non-orthogonal multiple
access (NOMA) systems, where the near user serves as a decode-and-forward (DF) relay …
