Tensor-Based Dynamic Channel Estimation for mmWave Movable Antenna MIMO Systems
Zhendong Li, Linchu Chen, Lin Chen +5
This paper investigates the dynamic channel estimation algorithm in mmWave movable antenna (MA) multiple-input multiple-output (MIMO) systems. To achieve highly accurate channel es…
Sensing for Reliable UAV Communication: Robust Trajectory and Resource Optimization in Low-Altitude Networks
Yifan Jiang, Qingqing Wu, Hongxun Hui +3
In low-altitude wireless networks, sensing-aided communication has emerged as a promising integrated sensing and communication (ISAC) paradigm for unmanned aerial vehicle (UAV) tra…
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…
Rotatable IRS Aided Wireless Communication
Qiaoyan Peng, Qingqing Wu, Guangji Chen +4
Rotatable intelligent reflecting surface (IRS) introduces a new spatial degree of freedom (DoF) by dynamically adjusting orientations without the need of changing its elements' pos…
Active IRS Assisted Joint Uplink and Downlink Communications
Qiaoyan Peng, Qingqing Wu, Guangji Chen +2
In this paper, we investigate an intelligent reflecting surface (IRS) aided wireless communication system, where active IRSs (AIRSs) are deployed to assist communication between a…
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…
