Covert Wireless Communications under Quasi-Static Fading with Channel Uncertainty
Khurram Shahzad, Xiangyun Zhou
Covert communications enable a transmitter to send information reliably in the presence of an adversary, who looks to detect whether the transmission took place or not. We consider…
Covert Wireless Communication in Presence of a Multi-Antenna Adversary and Delay Constraints
Khurram Shahzad, Xiangyun Zhou, Shihao Yan
Covert communication hides the transmission of a message from a watchful adversary while ensuring reliable information decoding at the receiver, providing enhanced security in wire…
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…
Covert Communications with A Full-Duplex Receiver over Wireless Fading Channels
Jinsong Hu, Khurram Shahzad, Shihao Yan +3
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 cover…
Covert Communication in Fading Channels under Channel Uncertainty
Khurram Shahzad, Xiangyun Zhou, Shihao Yan
A covert communication system under block fading channels is considered where users experience uncertainty about their channel knowledge. The transmitter seeks to hide the covert c…
Optimal Scheduling for Energy Harvesting Transmitters with Hybrid Energy Storage
Omur Ozel, Khurram Shahzad, Sennur Ulukus
We consider data transmission with an energy harvesting transmitter which has a hybrid energy storage unit composed of a perfectly efficient super-capacitor (SC) and an inefficient…
