Time-Division Energy Beamforming for Multiuser Wireless Power Transfer with Non-Linear Energy Harvesting
Ganggang Ma, Jie Xu, Ya-Feng Liu +1
Energy beamforming has emerged as a promising technique for enhancing the energy transfer efficiency of wireless power transfer (WPT). However, the performance of conventional ener…
Joint Transmit and Reflective Beamforming Design for IRS-Assisted Multiuser MISO SWIPT Systems
Yizheng Tang, Ganggang Ma, Hailiang Xie +2
This paper studies an intelligent reflecting surface (IRS)-assisted multiuser multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) syste…
Cognitive Wireless Power Transfer in the Presence of Reactive Primary Communication User
Tianxin Feng, Ganggang Ma, Jie Xu
This paper studies a cognitive or secondary multi-antenna wireless power transfer (WPT) system over a multi-carrier channel, which shares the same spectrum with a primary wireless…
A Generic Receiver Architecture for MIMO Wireless Power Transfer with Non-Linear Energy Harvesting
Ganggang Ma, Jie Xu, Yong Zeng +1
This letter investigates a multiple-input multiple-output (MIMO) wireless power transfer (WPT) system under practical non-liner energy harvesting (EH) models. We propose a new gene…
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…
