Bayesian Self-Calibration and Parametric Channel Estimation for 6G Antenna Arrays
Patrick Hödl, Jakob Möderl, Erik Leitinger +1
Accurate channel estimation is essential for both high-rate communication and high-precision sensing in 6G wireless systems. However, a major performance limitation arises from cal…
Integrated Real-Time Testbed for Wideband RFID and Wireless Power Transfer
Lukas D'Angelo, Daniel Pöhl, Benjamin Deutschmann +2
This contribution presents an experimental integrated real-time 8 x 8 distributed MIMO (D-MIMO) testbed for wideband backscatter communication (BSC) and wireless power transfer (WP…
Soft-Coherent Direct Multipath SLAM
Benjamin J. B. Deutschmann, Klaus Witrisal, Erik Leitinger
Challenging indoor and urban environments with severe multipath propagation and obstructed line-of-sight degrade classical radio positioning. Multipath-based simultaneous localizat…
Probabilistic Occupancy Grid for Radio-Based SLAM
Xuhong Li, Erik Leitinger, Fredrik Tufvesson +1
Sensing is an integral part of 6G and beyond systems, providing exceptional environmental perception along with communication. Radio frequency (RF)-based sensing often relies on si…
A Variational Message Passing Framework for Multi-Sensor Multi-Object Tracking using Raw Radar Signals
Anders Malthe Westerkam, Jakob Möderl, Erik Leitinger +1
The growing proliferation of unmanned aerial vehicles (UAVs) poses major challenges for reliable airspace surveillance, as drones are typically small, have low radar cross-sections…
Multi-Sensor Fusion for Extended Object Tracking Exploiting Active and Passive Radio Signals
Hong Zhu, Alexander Venus, Erik Leitinger +1
Reliable and robust positioning of radio devices remains a challenging task due to multipath propagation, hardware impairments, and interference from other radio transmitters. A fr…
