Determining Joint Periodicities in Multi-time Data With Sampling Uncertainties
David Svedberg, Filip Elvander, Andreas Jakobsson
In this work, we introduce a novel approach for determining a joint sparse spectrum from several non-uniformly sampled data sets, where each data set is assumed to have its own, po…
Defining Fundamental Frequency for Almost Harmonic Signals
Filip Elvander, Andreas Jakobsson
In this work, we consider the modeling of signals that are almost, but not quite, harmonic, i.e., composed of sinusoids whose frequencies are close to being integer multiples of a…
On Harmonic Approximations of Inharmonic Signals
Filip Elvander, Jie Ding, Andreas Jakobsson
In this work, we present the misspecified Gaussian Cramér-Rao lower bound for the parameters of a harmonic signal, or pitch, when signal measurements are collected from an almost,…
Mismatched Estimation of Polynomially Damped Signals
Filip Elvander, Johan Swärd, Andreas Jakobsson
In this work, we consider the problem of estimating the parameters of polynomially damped sinusoidal signals, commonly encountered in, for instance, spectroscopy. Generally, findin…
Multi-Marginal Optimal Mass Transport with Partial Information
Filip Elvander, Isabel Haasler, Andreas Jakobsson +1
During recent decades, there has been a substantial development in optimal mass transport theory and methods. In this work, we consider multi-marginal problems wherein only partial…
Non-Coherent Sensor Fusion via Entropy Regularized Optimal Mass Transport
Filip Elvander, Isabel Haasler, Andreas Jakobsson +1
This work presents a method for information fusion in source localization applications. The method utilizes the concept of optimal mass transport in order to construct estimates of…
