Compressed-Sensing-Based 3D Localization with Distributed Passive Reconfigurable Intelligent Surfaces

Jiguang He, Aymen Fakhreddine, Henk Wymeersch, George C. Alexandropoulos

ICASSP 2023accepted

In this paper, the programmable signal propagation paradigm, enabled by Reconfigurable Intelligent Surfaces (RISs), is exploited for high accuracy 3-Dimensional (3D) user localization with a single multi-antenna base station. Capitalizing on the tunable reflection capability of passive RISs, we pres…

Joint Channel and Direction Estimation for Ground-to-UAV Communications Enabled by a Simultaneous Reflecting and Sensing RIS

Jiguang He, Aymen Fakhreddine, George C. Alexandropoulos

ICASSP 2023accepted

Hybrid Reconfigurable Intelligent Surfaces (HRISs), which are capable of simultaneous programmable reflections and sensing, are expected to play a significant role in future wireless networks, enabling various Integrated Sensing and Communication (ISAC) applications. In this paper, we focus on HRIS-…
