Non-Reciprocal Reconfigurable Intelligent Surfaces
Jiaqi Xu, Haoyu Wang, Rang Liu +2
In contrast to conventional RIS, the scattering matrix of a non-reciprocal RIS (NR-RIS) is non-symmetric, leading to differences in the uplink and the downlink components of NR-RIS…
CRB Optimization using a Parametric Scattering Model for Extended Targets in ISAC Systems
Rang Liu, A. Lee Swindlehurst, Ming Li
This paper presents a novel parametric scattering model (PSM) for sensing extended targets in integrated sensing and communication (ISAC) systems. The PSM addresses the limitations…
Joint Space-Time Adaptive Processing and Beamforming Design for Cell-Free ISAC Systems
Rang Liu, Ming Li, Qian Liu
In this paper, we explore cooperative sensing and communication within cell-free integrated sensing and communication (ISAC) systems. Specifically, multiple transmit access points…
DOA Estimation-Oriented Joint Array Partitioning and Beamforming Designs for ISAC Systems
Rang Liu, Ming Li, Qian Liu +1
Integrated sensing and communication has been identified as an enabling technology for forthcoming wireless networks. In an effort to achieve an improved performance trade-off betw…
Active Reconfigurable Intelligent Surface Empowered Synthetic Aperture Radar Imaging
Yifan Sun, Rang Liu, Zhiping Lu +3
Synthetic Aperture Radar (SAR) utilizes the movement of the radar antenna over a specific area of interest to achieve higher spatial resolution imaging. In this paper, we aim to in…
Dynamic Hybrid Beamforming Designs for ELAA Near-Field Communications
Mengzhen Liu, Ming Li, Rang Liu +1
Extremely large-scale antenna array (ELAA) is a key candidate technology for the sixth generation (6G) mobile networks. Nevertheless, using substantial numbers of antennas to trans…
