Second-Order Asymptotics for Covert Communication over Quasi-Static Multiple-Antenna Fading Channels
Changhong Liu, Jingjing Wang, Qiaosheng Zhang +2
We study the second-order asymptotics of optimal codes for covert communication over quasi-static multi-antenna fading channels, under the covertness metric of Kullback--Leibler (K…
MIMO Radar Meets Polarization-Reconfigurable Antennas: A BCRB Perspective
Jinpeng Xu, Shuowen Zhang
In this paper, we investigate a novel multiple-input multiple-output (MIMO) radar system aided by phase shifter based polarization-reconfigurable antennas (PRAs). Specifically, a b…
Collaborative Secret and Covert Communications for Multi-User Multi-Antenna Uplink UAV Systems: Design and Optimization
Jinpeng Xu, Lin Bai, Xin Xie +1
Motivated by diverse secure requirements of multi-user in UAV systems, we propose a collaborative secret and covert transmission method for multi-antenna ground users to unmanned a…
The Dispersion of Broadcast Channels With Degraded Message Sets Using Gaussian Codebooks
Zhuangfei Wu, Lin Bai, Jinpeng Xu +2
We study the two-user broadcast channel with degraded message sets and derive second-order achievability rate regions. Specifically, the channel noises are not necessarily Gaussian…
