Low-Altitude ISAC with Rotatable Active and Passive Arrays
Ziyuan Zheng, Qingqing Wu, Yanze Zhu +4
This paper investigates a low-altitude integrated sensing and communication (ISAC) system that leverages cooperative rotatable active and passive arrays. We consider a downlink sce…
Semi-Passive IRS Enabled Sensing with Group Movable Sensors
Qiaoyan Peng, Qingqing Wu, Wen Chen +4
The performance of the sensing system is limited by the signal attenuation and the number of receiving components. In this letter, we investigate the sensor position selection in a…
Movable Intelligent Surface-Enabled Wireless Communications: Static Phase Shifts with Mechanical Reconfigurability
Ziyuan Zheng, Qingqing Wu, Wen Chen +2
Intelligent surfaces that reshape electromagnetic waves are regarded as disruptive technologies for wireless networks. However, existing designs sit at two costly extremes: dynamic…
Reconfigurable Airspace: Synergizing Movable Antenna and Intelligent Surface for Low-Altitude ISAC Networks
Honghao Wang, Qingqing Wu, Yifan Jiang +7
Low-altitude unmanned aerial vehicle (UAV) networks are integral to future 6G integrated sensing and communication (ISAC) systems. However, their deployment is hindered by challeng…
Rotatable Antenna Enabled Spectrum Sharing: Joint Antenna Orientation and Beamforming Design
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +3
Conventional antenna arrays rely primarily on digital beamforming for spatial control. While adding more elements can narrow beamwidth and suppress interference, such scaling incur…
Wireless Sensing with Movable Intelligent Surface
