Probabilistic Accumulate-then-Transmit in Wireless-Powered Covert Communications
Yida Wang, Shihao Yan, Weiwei Yang +2
In this paper, we investigate the optimal design of a wireless-powered covert communication (WP-CC) system, in which a probabilistic accumulate-then-transmit (ATT) protocol is prop…
Intelligent Reflecting Surface for Wireless Communication Security and Privacy
Shihao Yan, Xiaobo Zhou, Derrick Wing Kwan Ng +2
Intelligent reflection surface (IRS) is emerging as a promising technique for future wireless communications. Considering its excellent capability in customizing the channel condit…
Optimal Transmit Power and Flying Location for UAV Covert Wireless Communications
Shihao Yan, Stephen V. Hanly, Iain B. Collings
This paper jointly optimizes the flying location and wireless communication transmit power for an unmanned aerial vehicle (UAV) conducting covert operations. This is motivated by a…
Covert Communications with Constrained Age of Information
Yida Wang, Shihao Yan, Weiwei Yang +1
In this letter, we consider the requirement of information freshness in covert communications for the first time. With artificial noise (AN) generated from a full-duplex (FD) recei…
Joint Beam Training and Data Transmission Design for Covert Millimeter-Wave Communication
Jiayu Zhang, Min Li, Shihao Yan +4
Covert communication prevents legitimate transmission from being detected by a warden while maintaining certain covert rate at the intended user. Prior works have considered the de…
On the Pilot Contamination Attack in Multi-Cell Multiuser Massive MIMO Networks
Noman Akbar, Shihao Yan, Asad Masood Khattak +1
In this paper, we analyze pilot contamination (PC) attacks on a multi-cell massive multiple-input multiple-output (MIMO) network with correlated pilots. We obtain correlated pilots…
