Compressed Sensing for Reconstructing Coherent Multidimensional Spectra
Zhengjun Wang, Shiwen Lei, Khadga Jung Karki +2
We apply two sparse reconstruction techniques, the least absolute shrinkage and selection operator (LASSO) and the sparse exponential mode analysis (SEMA), to two-dimensional (2D)…
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…
