Multiobjective Preexpectation Reasoning for Probabilistic Programs
Lena Verscht, Hannah Mertens, Kevin Batz +3
Probabilistic programs with nondeterminism model planning problems in which a strategy resolves the nondeterminism to optimize an expected outcome. We study the multiobjective sett…
Multi-User Localization via Active Sensing with Electromagnetically Reconfigurable Antennas
Ruizhi Zhang, Yuchen Zhang, Ying Zhang +1
The paper proposes an active‑sensing framework for multi‑user uplink localization that adaptively configures shared electromagnetically reconfigurable antennas using past pilot obs…
On-Site Beam Calibration for RIS-Aided Positioning Systems
Mengting Li, Hui Chen, Sigurd S. Petersen +5
High precision positioning is a key enabler for next-generation communication applications such as smart transportation and augmented reality. Reconfigurable intelligent surface (R…
HoloTrace: a Location Privacy-Preserving Framework for mmWave MIMO-OFDM Systems
Lorenzo Italiano, Alireza Pourafzal, Hui Chen +4
The paper proposes HoloTrace, a framework that lets user devices spoof location-related signal parameters in mmWave MIMO‑OFDM systems to prevent base stations from accurately estim…
Amplitude-Independent Robust Snapshot 6-D Radio SLAM via a Uniffed Angle-Delay Formulation
Shengqiang Shen, Aoyun Hao, Weihao Geng +3
This paper addresses bistatic snapshot radio SLAM, in which a user equipment (UE) with unknown 6-D pose and clock bias is localized and environmental landmarks are reconstructed fr…
Active Sensing for RIS-Aided Tracking and Power Control: A Hybrid Neuroevolution and Supervised Learning Approach
George Stamatelis, Hui Chen, Henk Henk Wymeersch +1
This paper studies energy efficient tracking of power-limited mobile users with the assistance of a Reconfigurable Intelligent Surface (RIS). Since localization pilot transmissions…
