Graph-based Simultaneous Localization and Bias Tracking
Alexander Venus, Erik Leitinger, Stefan Tertinek +2
We present a factor graph formulation and particle-based sum-product algorithm for robust localization and tracking in multipath-prone environments. The proposed sequential algorit…
Super-Resolution Estimation of UWB Channels including the Diffuse Component -- An SBL-Inspired Approach
Stefan Grebien, Erik Leitinger, Klaus Witrisal +1
In this paper, we present an iterative algorithm that detects and estimates the specular components and estimates the diffuse component of single-input-multiple-output (SIMO) ultra…
A Neural-enhanced Factor Graph-based Algorithm for Robust Positioning in Obstructed LOS Situations
Alexander Venus, Erik Leitinger, Stefan Tertinek +1
This paper presents a neural-enhanced probabilistic model and corresponding factor graph-based sum-product algorithm for robust localization and tracking in multipath-prone environ…
Fast Variational Block-Sparse Bayesian Learning
Jakob Möderl, Erik Leitinger, Bernard H. Fleury +2
We propose a variational Bayesian (VB) implementation of block-sparse Bayesian learning (BSBL) to compute proxy probability density functions (PDFs) that approximate the posterior…
Propagation Modeling for Physically Large Arrays: Measurements and Multipath Component Visibility
Thomas Wilding, Benjamin J. B. Deutschmann, Christian Nelson +3
This paper deals with propagation and channel modeling for physically large arrays. The focus lies on acquiring a spatially consistent model, which is essential, especially for pos…
Bistatic MIMO Radar Sensing of Specularly Reflecting Surfaces for Wireless Power Transfer
Benjamin J. B. Deutschmann, Maximilian Graber, Thomas Wilding +1
Geometric environment information aids future distributed radio infrastructures in providing services, such as ultra-reliable communication, positioning, and wireless power transfe…
Variational Inference of Structured Line Spectra Exploiting Group-Sparsity
Jakob Möderl, Franz Pernkopf, Klaus Witrisal +1
In this paper, we present a variational inference algorithm that decomposes a signal into multiple groups of related spectral lines. The spectral lines in each group are associated…
Uplink Joint Positioning and Synchronization in Cell-Free Deployments with Radio Stripes
Alessio Fascista, Benjamin J. B. Deutschmann, Musa Furkan Keskin +6
Radio stripes (RSs) is an emerging technology in beyond 5G and 6G wireless networks to support the deployment of cell-free architectures. In this paper, we investigate the potentia…
