Phase-Optimized K-SVD for Signal Extraction from Underdetermined Multichannel Sparse Mixtures
Antoine Deleforge, Walter Kellermann
We propose a novel sparse representation for heavily underdetermined multichannel sound mixtures, i.e., with much more sources than microphones. The proposed approach operates in t…

Improving Blind Source Separation Performance By Adaptive Array Geometries For Humanoid Robots
Hendrik Barfuss, Walter Kellermann
In this paper, the concept of an adaptation algorithm is proposed, which can be used to blindly adapt the microphone array geometry of a humanoid robot such that the performance of…
