Pilot-Based Channel Estimation Design in Covert Wireless Communication
Tingzhen Xu, Linlin Sun, Shihao Yan +2
In this work, for the first time, we tackle channel estimation design with pilots in the context of covert wireless communication. Specifically, we consider Rayleigh fading for the…
Covert Communication with A Full-Duplex Receiver Based on Channel Distribution Information
Tingzhen Xu, Ling Xu, Xiaoyu Liu +1
In this work, we consider a system of covert communication with the aid of a full-duplex (FD) receiver to enhance the performance in a more realistic scenario, i.e., only the chann…
High-performance Power Allocation Strategies for Secure Spatial Modulation
Feng Shu, Xiaoyu Liu, Guiyang Xia +3
Optimal power allocation (PA) strategies can make a significant rate improvement in secure spatial modulation (SM). Due to the lack of secrecy rate (SR) closed-form expression in s…
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…
