Energy Efficient Design in IRS-Assisted UAV Data Collection System under Malicious Jamming
Zhi Ji, Jia Tu, Xinrong Guan +3
In this paper, we study an unmanned aerial vehicle (UAV) enabled data collection system, where an intelligent reflecting surface (IRS) is deployed to assist in the communication fr…
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…
Energy-Efficient Trajectory Design for UAV-Enabled Communication Under Malicious Jamming
Yang Wu, Weiwei Yang, Xinrong Guan +1
In this letter, we investigate a UAV-enabled communication system, where a UAV is deployed to communicate with the ground node (GN) in the presence of multiple jammers. We aim to m…
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…
Robust and Secure Beamforming for Intelligent Reflecting Surface Aided mmWave MISO Systems
Xingbo Lu, Weiwei Yang, Xinrong Guan +2
In this letter, we investigate the robust and secure beamforming (RSBF) in an intelligent reflecting surface (IRS) aided millimeter wave (mmWave) multiple input single output (MISO…
Wireless Key Generation from Imperfect Channel State Information: Performance Analysis and Improvements
Xinrong Guan, Ning Ding, Yueming Cai +1
The basis of generating secret key from the common wireless channel at two communication parties is reciprocity. However, due to non-simultaneous measurements and unavoidable estim…
