Hardware architecture for ultra-wideband channel impulse response measurements using compressed sensing. - In: 28th European Signal Processing Conference (EUSIPCO 2020) : proceedings : 24-28 August 2020, Amsterdam, The Nederlands.. - [Piscataway, NJ] : IEEE, (2020), S. 1663-1667

We propose a compact hardware architecture for measuring sparse channel impulse responses (IR) by extending the M-Sequence ultra-wideband (UWB) measurement principle with the concept of compressed sensing. A channel is excited with a periodic M-sequence and its response signal is observed using a Random Demodulator (RD), which observes pseudo-random linear combinations of the response signal at a rate significantly lower than the measurement bandwidth. The excitation signal and the RD mixing signal are generated from compactly implementable Linear Feedback Shift registers (LFSR) and operated from a common clock. A linear model is derived that allows retrieving an IR from a set of observations using Sparse-Signal-Recovery (SSR). A Matrix-free model implementation is possible due to the choice of synchronous LFSRs as signal generators, resulting in low computational complexity. For validation, real measurement data of a time-variant channel containing multipath components is processed by simulation models of our proposed architecture and the classic M-Sequence method. We show successful IR recovery using our architecture and SSR, outperforming the classic method significantly in terms of IR measurement rate. Compared to the classic method, the proposed architecture allows faster measurements of sparse time-varying channels, resulting in higher Doppler tolerance without increasing hardware or data stream complexity.

Stochastic modeling of short and long term clock skew. - In: IEEE IFCS-ISAF 2020 : Joint Conference of the IEEE International Frequency Control Symposium & IEEE International Symposium on Applications of Ferroelectrics : virtual conference, July 19-23, 2020 : 2020 symposium proceedings.. - Piscataway, NJ : IEEE, (2020), insges. 4 S.

Traditional black box clock skew models are either the power-law noise model or a more recent approach based on auto-regressive (AR) filters. Unfortunately, neither algorithm can accurately model short and long term skew due to limited degrees of freedom or stability constraints. We propose a novel model that employs the current AR algorithm recursively with appropriate pre- and post-processing to achieve numeric stability and accurate reproduction of short and long term effects. The model coefficients are derived from a measured skew signal, with the model output matching an exemplary original signal closely in terms of Allan variance and time-domain behavior.

Acoustic process monitoring in laser beam welding. - In: Procedia CIRP. - Amsterdam [u.a.] : Elsevier, ISSN 2212-8271, Bd. 94 (2020), S. 763-768

Structure-borne acoustic emission (AE) measurement shows major advantages regarding quality assurance and process control in industrial applications. In this paper, laser beam welding of steel and aluminum was carried out under varying process parameters (welding speed, focal position) in order to provide data by means of structure-borne AE and simultaneously high-speed video recordings. The analysis is based on conventionally (e.g. filtering, autocorrelation, spectrograms) as well as machine learning methods (convolutional neural nets) and showed promising results with respect to the use of structure-borne AE for process monitoring using the example of spatter formation.

Im Rahmen dieser Dissertation wird die Kanalmodellierung von zeitvarianten, frequenzselektiven Mehrnutzer Multiple Input Multiple Output (MIMO) Kanälen für die Funkübertragung behandelt. Durch eine Erweiterung der Bello Funktionen mit Hilfe von Tensoren wird die multidimensionale Dispersion des Funkkanals dargestellt. Es werden einige der wichtigsten Ansätze zur Kanalmodellierung vorgestellt und klassifiziert. Für geometrische Kanalmodelle ist es entscheidend die Richtcharakteristika der Antennen im Fernfeld genau und effizient zu beschreiben. Zu diesem Zweck wird ein neues Beschreibungsverfahren entwickelt, das auf der Discrete Vector Spherical Fourier Transform (DVSFT) basiert. Dadurch ist es möglich, eine höhere Genauigkeit bei der Beschreibung von komplexen Vektorfunktionen auf der Kugel zu erreichen. Die vorgeschlagene Methode führt zu neuen Anwendungsmöglichkeiten. Der Schwerpunkt dieser Dissertation ist IlmProp: ein Geometrie-basiertes Framework zur Kanalmodellierung. Es füllt die Lücke zwischen konventionellen direktionalen Kanalmodellen und so genannten "Ray-Tracer"Kanalmodellen. IlmProp ermöglicht es gleichzeitig mehrere Nutzer in der selben Umgebung zu simulieren. Mehrwege-Komponenten werden an Hand von punktförmigen Wechselwirkungsobjekten, so genannten Interacting Objects (IOs), modelliert. Dadurch wird die zeitliche Variation der Korrelation in Zeit, Frequenz, Raum und zwischen den Nutzern realitätsnah modelliert. Die Parameter des IlmProp Kanalmodells können willkürlich gesetzt oder aus hochauflösenden Parameterschatzverfahren gewonnen werden. Im ersten Fall kann IlmProp dazu genutzt werden, verschiedene Sende, Empfangs und SchedulingAlgorithmen zu testen. Um aus hochauflosenden Parameterschatzungen die IlmPropParameter zu gewinnen, wurde ein neuartiger Algorithmus entwickelt, der die IOs aus Einfalls- und Austritts-winkel und der Ausbreitungszeit lokalisiert.Dies macht IlmProp zu einem leistungsfähigen Visualisierungswerkzeug, um Kanalmessungen zu validieren und um die Ausbreitungsbedingung des Szenarios zu untersuchen. Im weiteren Verlauf der Arbeit wird das so genannte Measurement-Based Parametric Channel Model (MBPCM), verbessert. Es ermöglicht durch eine antennenunabhängige, doppelt-direktionale Kanalbeschreibung, aus vorhandenen Kanalmessungen zusätzliche realitätsnahe, synthetische Kanalrealisierungen zu erzeugen.
