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 …

This paper jointly optimizes the flying location and wireless communication transmit power
for an unmanned aerial vehicle (UAV) conducting covert operations. This is motivated by …

Communication performance relies largely on the availability of channel state information
(CSI). This paper investigates the impact of outdated CSI on the achievable covert …

The problem of covert communication over Multiple-Input Multiple-Output (MIMO) Additive
White Gaussian Noise (AWGN) channels is investigated, in which a transmitter attempts to …

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

In this work, we study a covert communication scheme in which some users are
opportunistically selected to emit interference signals for the purpose of hiding the …

In this paper, we investigate the optimal probabilistic constellation shaping design for covert
communication systems from a practical view. Different from conventional covert …

Driven by the ever-increasing requirements of ultra-high spectral efficiency, ultra-low
latency, and massive connectivity, the forefront of wireless research calls for the design of …

We study the effect of node mobility on the throughput scaling of the covert communication
over a wireless adhoc network. It is assumed that n mobile nodes want to communicate each …

This work investigates wireless covert communication in a multi-sensor asymmetric noise
scenario. We adopt KL (Kullback–Leibler) divergence as the covertness constraint metric …
