Extrapolation of Bandlimited Multidimensional Signals from Continuous Measurements
Cornelius Frankenbach, Pablo Martínez-Nuevo, Martin Møller +1
Conventional sampling and interpolation commonly rely on discrete measurements. In this paper, we develop a theoretical framework for extrapolation of signals in higher dimensions…
Faster IVA: Update Rules for Independent Vector Analysis based on Negentropy and the Majorize-Minimize Principle
Andreas Brendel, Walter Kellermann
Algorithms for Blind Source Separation (BSS) of acoustic signals require efficient and fast converging optimization strategies to adapt to nonstationary signal statistics and time-…
A Unified Bayesian View on Spatially Informed Source Separation and Extraction based on Independent Vector Analysis
Andreas Brendel, Thomas Haubner, Walter Kellermann
Signal separation and extraction are important tasks for devices recording audio signals in real environments which, aside from the desired sources, often contain several interferi…
Spatially Informed Independent Vector Analysis
Andreas Brendel, Thomas Haubner, Walter Kellermann
We present a Maximum A Posteriori (MAP) derivation of the Independent Vector Analysis (IVA) algorithm, a blind source separation algorithm, by incorporating a prior over the demixi…
