AI-enabled STAR-RIS aided MISO ISAC Secure Communications

no code implementations26 Feb 2024 Zhengyu Zhu, Mengfei Gong, Gangcan Sun, Peijia Liu, De Mi

A simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided integrated sensing and communication (ISAC) dual-secure communication system is studied in this paper.

Adaptive-avg-pooling based Attention Vision Transformer for Face Anti-spoofing

no code implementations10 Jan 2024 Jichen Yang, Fangfan Chen, Rohan Kumar Das, Zhengyu Zhu, Shunsi Zhang

In this work, we propose a novel vision transformer referred to as adaptive-avg-pooling based attention vision transformer (AAViT) that uses modules of adaptive average pooling and attention to replace the module of average value computing.

Intelligent Reflective Surface Assisted Integrated Sensing and Wireless Power Transfer

no code implementations13 Sep 2023 Zheng Li, Zhengyu Zhu, Zheng Chu, Yingying Guan, De Mi, Fan Liu, Lie-Liang Yang

Wireless sensing and wireless energy are enablers to pave the way for smart transportation and a greener future.

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 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.
