Estimating parameters of nonlinear systems using the elitist particle filter based on evolutionary strategies
Christian Huemmer, Christian Hofmann, Roland Maas +1
In this article, we present the elitist particle filter based on evolutionary strategies (EPFES) as an efficient approach for nonlinear system identification. The EPFES is derived…
On the Impact of Localization Errors on HRTF-based Robust Least-Squares Beamforming
Hendrik Barfuss, Walter Kellermann
In this work, a recently proposed Head-Related Transfer Function (HRTF)-based Robust Least-Squares Frequency-Invariant (RLSFI) beamformer design is analyzed with respect to its rob…
Towards a Generalization of Relative Transfer Functions to More Than One Source
Antoine Deleforge, Sharon Gannot, Walter Kellermann
We propose a natural way to generalize relative transfer functions (RTFs) to more than one source. We first prove that such a generalization is not possible using a single multicha…
Binaural coherent-to-diffuse-ratio estimation for dereverberation using an ITD model
Chengshi Zheng, Andreas Schwarz, Walter Kellermann +1
Most previously proposed dual-channel coherent-to-diffuse-ratio (CDR) estimators are based on a free-field model. When used for binaural signals, e.g., for dereverberation in binau…
Coherent-to-Diffuse Power Ratio Estimation for Dereverberation
Andreas Schwarz, Walter Kellermann
The estimation of the time- and frequency-dependent coherent-to-diffuse power ratio (CDR) from the measured spatial coherence between two omnidirectional microphones is investigate…
