Wireless Propagation Parameter Estimation with Convolutional Neural Networks
Steffen Schieler, Sebastian Semper, Reiner Thomä
Wireless channel propagation parameter estimation forms the foundation of channel sounding, estimation, modeling, and sensing. This paper introduces a Deep Learning approach for jo…
Misspecification of Multiple Scattering in Scalar Wave Fields and its Impact in Ultrasound Tomography
Eduardo Pérez, Sebastian Semper, Sayako Kodera +2
In this work, we investigate the localization of targets in the presence of multiple scattering. We focus on the often omitted scenario in which measurement data is affected by mul…
Improving the Spatial Correlation Characteristics of Antenna Arrays using Linear Operators and Wide-band Modelling
Marc Miranda, Sebastian Semper, Michael Döbereiner +1
The analysis of wireless communication channels at the mmWave, sub-THz and THz bands gives rise to difficulties in the construction of antenna arrays due to the small maximum inter…
A Framework for Developing and Evaluating Algorithms for Estimating Multipath Propagation Parameters from Channel Sounder Measurements
Akbar Sayeed, Damla Guven, Michael Doebereiner +4
A framework is proposed for developing and evaluating algorithms for extracting multipath propagation components (MPCs) from measurements collected by channel sounders at millimete…
Estimating Multi-Modal Dense Multipath Components using Auto-Encoders
Steffen Schieler, Michael Döbereiner, Sebastian Semper +1
We present a maximum-likelihood estimation algorithm for radio channel measurements exhibiting a mixture of independent Dense Multipath Components. The novelty of our approach is i…
Frequency Sub-Sampling of Ultrasound Non-Destructive Measurements: Acquisition, Reconstruction and Performance
Jan Kirchhof, Sebastian Semper, Christoph W. Wagner +3
In ultrasound nondestructive testing, a widespread approach is to take synthetic aperture measurements from the surface of a specimen to detect and locate defects within it. Based…
