A Belief Propagation Approach for Direct Multipath-Based SLAM
Mingchao Liang, Erik Leitinger, Florian Meyer
In this work, we develop a multipath-based simultaneous localization and mapping (SLAM) method that can directly be applied to received radio signals. In existing multipath-based S…
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…
Multipath-based SLAM for Non-Ideal Reflective Surfaces Exploiting Multiple-Measurement Data Association
Lukas Wielandner, Alexander Venus, Thomas Wilding +1
Multipath-based simultaneous localization and mapping (SLAM) is a promising approach to obtain position information of transmitters and receivers as well as information regarding t…
Self-attention for Enhanced OAMP Detection in MIMO Systems
Alexander Fuchs, Christian Knoll, Nima N. Moghadam +3
Multiple-Input Multiple-Output (MIMO) systems are essential for wireless communications. Sinceclassical algorithms for symbol detection in MIMO setups require large computational r…
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…
Message Passing-Based 9-D Cooperative Localization and Navigation with Embedded Particle Flow
Lukas Wielandner, Erik Leitinger, Florian Meyer +1
Cooperative localization (CL) is an important technology for innovative services such as location-aware communication networks, modern convenience, and public safety. We consider w…
