Achieving Covert Wireless Communications Using a Full-Duplex Receiver
Khurram Shahzad, Xiangyun Zhou, Shihao Yan +3
Covert communications hide the transmission of a message from a watchful adversary while ensuring a certain decoding performance at the receiver. In this work, a wireless communica…
Gaussian Signalling for Covert Communications
Shihao Yan, Yirui Cong, Stephen Hanly +1
In this work, we examine the optimality of Gaussian signalling for covert communications with an upper bound on or as th…
Optimal Compression and Transmission Rate Control for Node-Lifetime Maximization
Sheeraz A. Alvi, Xiangyun Zhou, Salman Durrani
We consider a system that is composed of an energy constrained sensor node and a sink node, and devise optimal data compression and transmission policies with an objective to prolo…
Covert Wireless Communications with Channel Inversion Power Control in Rayleigh Fading
Jinsong Hu, Shihao Yan, Xiangyun Zhou +2
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 and p…
