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…
Delay-Constrained Covert Communications with A Full-Duplex Receiver
Feng Shu, Tingzhen Xu, Jinsong Hu +1
In this work, we consider delay-constrained covert communications with the aid of a full-duplex (FD) receiver. Without delay constraints, it has been shown that the transmit power…
Secure Transmission to the Strong User with Optimal Power Allocation in NOMA
