Intelligent Reflecting Surface (IRS)-Aided Covert Wireless Communications with Delay Constraint
Xiaobo Zhou, Shihao Yan, Qingqing Wu +2
This work examines the performance gain achieved by deploying an intelligent reflecting surface (IRS) in covert communications. To this end, we formulate the joint design of the tr…
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…
Neural Network Architectures for Location Estimation in the Internet of Things
Ihsan Ullah, Robert Malaney, Shihao Yan
Artificial Intelligence (AI) solutions for wireless location estimation are likely to prevail in many real-world scenarios. In this work, we demonstrate for the first time how the…
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…
Truncated Channel Inversion Power Control to Enable One-Way URLLC with Imperfect Channel Reciprocity
Chunhui Li, Shihao Yan, Nan Yang +1
We propose to use channel inversion power control (CIPC) to achieve one-way ultra-reliable and low-latency communications (URLLC), where only the transmission in one direction requ…
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…
UAV-Enabled Confidential Data Collection in Wireless Networks
Xiaobo Zhou, Shihao Yan, Min Li +2
This work, for the first time, considers confidential data collection in the context of unmanned aerial vehicle (UAV) wireless networks, where the scheduled ground sensor node (SN)…
