Intelligent Reflecting Surface Assisted Integrated Sensing and Communications for mmWave Channels

no code implementations5 Jan 2022 Zhengyu Zhu, Zheng Li, Zheng Chu, Gangcan Sun, Wanming Hao, Pei Xiao, Inkyu Lee

By jointly designing the radar signal covariance (RSC) matrix, the beamforming vector of the communication system, and the IRS phase shift, the ISAC system transmission rate can be improved while matching the desired waveform for radar.

A Novel Transmission Policy for Intelligent Reflecting Surface Assisted Wireless Powered Sensor Networks

no code implementations28 Apr 2021 Zheng Chu, Pei Xiao, De Mi, Wanming Hao, Mohsen Khalily, Lie-Liang Yang

Our proposed policy for the considered WPSN is called IRS assisted harvest-then-transmit time switching, which is able to schedule the transmission time slots by switching between energy collection and energy reflection modes.

A Unified Framework for IRS Enabled Wireless Powered Sensor Networks

no code implementations19 Mar 2021 Zheng Chu, Zhengyu Zhu, Miao Zhang, Fuhui Zhou, Li Zhen, Xueqian Fu, and Naofal Al-Dhahir

To evaluate the performance of this IRS assisted WPSN, we are interested in maximizing its system sum throughput to jointly optimize the energy beamforming of the PS, the transmission time allocation, as well as the phase shifts of the WET and WIT phases.
