Proactive Eavesdropping via Jamming for Rate Maximization over Rayleigh Fading Channels
Jie Xu, Lingjie Duan, Rui Zhang
Instead of against eavesdropping, this letter proposes a new paradigm in wireless security by studying how a legitimate monitor (e.g., government agencies) efficiently eavesdrops a…
Multi-antenna Wireless Powered Communication with Co-channel Energy and Information Transfer
Yueling Che, Jie Xu, Lingjie Duan +1
This letter studies a multi-antenna wireless powered communication (WPC) system with co-channel energy and information transfer, where a wireless device (WD), powered up by wireles…
Energy Group-Buying with Loading Sharing for Green Cellular Networks
Jie Xu, Lingjie Duan, Rui Zhang
In the emerging hybrid electricity market, mobile network operators (MNOs) of cellular networks can make day-ahead energy purchase commitments at low prices and real-time flexible…
Multiuser MIMO Wireless Energy Transfer With Coexisting Opportunistic Communication
Jie Xu, Suzhi Bi, Rui Zhang
This letter considers spectrum sharing between a primary multiuser multiple-input multiple-output (MIMO) wireless energy transfer (WET) system and a coexisting secondary point-to-p…
A General Utility Optimization Framework for Energy Harvesting Based Wireless Communications
Hang Li, Jie Xu, Rui Zhang +1
In recent years, wireless communication systems are expected to achieve more cost-efficient and sustainable operations by replacing conventional fixed power supplies such as batter…
A General Design Framework for MIMO Wireless Energy Transfer with Limited Feedback
Jie Xu, Rui Zhang
Multi-antenna or multiple-input multiple-output (MIMO) technique can significantly improve the efficiency of radio frequency (RF) signal enabled wireless energy transfer (WET). To…
