Multi-User Localization via Active Sensing with Electromagnetically Reconfigurable Antennas
Ruizhi Zhang, Yuchen Zhang, Ying Zhang +1
This paper investigates multi-user localization in uplink wireless systems assisted by electromagnetically reconfigurable antennas (ERAs). Unlike traditional localization schemes,…
Tri-Hybrid Beamforming Design for ISAC Systems with Reconfigurable Antennas
Jiangong Chen, Xia Lei, Yuchen Zhang +2
Integrated Sensing and Communication (ISAC) systems require efficient beamforming architectures to jointly support communication and sensing functionalities. To reduce hardware ove…
User Localization via Active Sensing with Electromagnetically Reconfigurable Antennas
Ruizhi Zhang, Yuchen Zhang, Ying Zhang
This paper presents an end-to-end deep learning framework for electromagnetically reconfigurable antenna (ERA)-aided user localization with active sensing, where ERAs provide addit…
Precoding Matrix Indicator in the 5G NR Protocol: A Tutorial on 3GPP Beamforming Codebooks
Boyu Ning, Haifan Yin, Sixu Liu +8
This paper bridges this critical gap by providing a systematic examination of the beamforming codebook technology, i.e., precoding matrix indicator (PMI), in the 5G NR from theoret…
A Deep Learning Framework for Joint Channel Acquisition and Communication Optimization in Movable Antenna Systems
Ruizhi Zhang, Yuchen Zhang, Lipeng Zhu +2
This paper presents an end-to-end deep learning framework in a movable antenna (MA)-enabled multiuser communication system. In contrast to the conventional works assuming perfect c…
Joint Bistatic Positioning and Monostatic Sensing: Optimized Beamforming and Performance Tradeoff
Yuchen Zhang, Hui Chen, Pinjun Zheng +4
We investigate joint bistatic positioning (BP) and monostatic sensing (MS) within a multi-input multi-output orthogonal frequency-division system. Based on the derived Cramér-Rao B…
