Joint RIS Calibration and Multi-User Positioning
Yi Lu, Hui Chen, Jukka Talvitie +2
Reconfigurable intelligent surfaces (RISs) are expected to be a key component enabling the mobile network evolution towards a flexible and intelligent 6G wireless platform. In most…
Positioning and Sensing in 6G: Gaps, Challenges, and Opportunities
Ali Behravan, Vijaya Yajnanarayana, Musa Furkan Keskin +8
Among the key differentiators of 6G compared to 5G will be the increased emphasis on radio based positioning and sensing. These will be utilized not only for conventional location-…
Joint User Localization and Location Calibration of A Hybrid Reconfigurable Intelligent Surface
Reza Ghazalian, Hui Chen, George C. Alexandropoulos +3
The recent research in the emerging technology of reconfigurable intelligent surfaces (RISs) has identified its high potential for localization and sensing. However, to accurately…
Localization Coverage Analysis of THz Communication Systems with a 3D Array
Pinjun Zheng, Tarig Ballal, Hui Chen +2
This paper considers the problem of estimating the position and orientation of a user equipped with a three-dimensional (3D) array receiving downlink far-field THz signals from mul…
Doppler-Enabled Single-Antenna Localization and Mapping Without Synchronization
Hui Chen, Fan Jiang, Yu Ge +2
Radio localization is a key enabler for joint communication and sensing in the fifth/sixth generation (5G/6G) communication systems. With the help of multipath components (MPCs), l…
Channel Model Mismatch Analysis for XL-MIMO Systems from a Localization Perspective
Hui Chen, Ahmed Elzanaty, Reza Ghazalian +3
Radio localization is applied in high-frequency (e.g., mmWave and THz) systems to support communication and to provide location-based services without extra infrastructure. {For so…
