Capacity of UAV-Enabled Multicast Channel: Joint Trajectory Design and Power Allocation
Yundi Wu, Jie Xu, Ling Qiu +1
This paper studies an unmanned aerial vehicle (UAV)-enabled multicast channel, in which a UAV serves as a mobile transmitter to deliver common information to a set of ground us…
Proactive Eavesdropping via Jamming over HARQ-Based Communications
Jie Xu, Kai Li, Lingjie Duan +1
This paper studies the wireless surveillance of a hybrid automatic repeat request (HARQ) based suspicious communication link over Rayleigh fading channels. We propose a proactive e…
Exploiting Interference for Secrecy Wireless Information and Power Transfer
Yuan Liu, Jie Xu, Rui Zhang
Radio-frequency (RF) signals enabled wireless information and power transfer (WIPT) is a cost-effective technique to achieve two-way communications and at the same time provide ene…
UAV-Enabled Wireless Power Transfer: Trajectory Design and Energy Region Characterization
Jie Xu, Yong Zeng, Rui Zhang
This paper studies a new unmanned aerial vehicle (UAV)-enabled wireless power transfer (WPT) system, where a UAV-mounted energy transmitter (ET) broadcasts wireless energy to charg…
Wireless Surveillance of Two-Hop Communications
Ganggang Ma, Jie Xu, Lingjie Duan +1
Wireless surveillance is becoming increasingly important to protect the public security by legitimately eavesdropping suspicious wireless communications. This paper studies the wir…
Joint Computation and Communication Cooperation for Mobile Edge Computing
Xiaowen Cao, Feng Wang, Jie Xu +2
This paper proposes a novel joint computation and communication cooperation approach in mobile edge computing (MEC) systems, which enables user cooperation in both computation and…
