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…
Optimizing Sparse Antenna Arrays for Localization and Sensing using Vector Spherical Wave Functions
Tobias Lafer, Erik Leitinger, Klaus Witrisal
In increasing number of electronic devices implement wideband radio technologies for localization and sensing purposes, like ultra-wideband (UWB). Such radio technologies benefit f…
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…
Multi-Sensor Fusion of Active and Passive Measurements for Extended Object Tracking
Hong Zhu, Alexander Venus, Erik Leitinger +1
This paper addresses the challenge of achieving robust and reliable positioning of a radio device carried by an agent, in scenarios where direct line-of-sight (LOS) radio links are…
Geometry-Based Channel Estimation, Prediction, and Fusion
Benjamin J. B. Deutschmann, Erik Leitinger, Klaus Witrisal
Reciprocity-based beamforming-most commonly employed in time-division duplexing-uses noisy, estimated (i.e., measured) channel state information (CSI) acquired on the uplink. While…
Physically Large Apertures for Wireless Power Transfer: Performance and Regulatory Aspects
Benjamin J. B. Deutschmann, Ulrich Muehlmann, Ahmet Kaplan +7
Wireless power transfer (WPT) is a promising service for the Internet of Things, providing a cost-effective and sustainable solution to deploy so-called energy-neutral devices on a…
