Robust Joint Estimation of Multi-Microphone Signal Model Parameters
Andreas I. Koutrouvelis, Richard C. Hendriks, Richard Heusdens +1
One of the biggest challenges in multi-microphone applications is the estimation of the parameters of the signal model such as the power spectral densities (PSDs) of the sources, t…
A Convex Approximation of the Relaxed Binaural Beamforming Optimization Problem
Andreas I. Koutrouvelis, Richard C. Hendriks, Richard Heusdens +1
The recently proposed relaxed binaural beamforming (RBB) optimization problem provides a flexible trade-off between noise suppression and binaural-cue preservation of the sound sou…
A Low-Cost Robust Distributed Linearly Constrained Beamformer for Wireless Acoustic Sensor Networks with Arbitrary Topology
Andreas I. Koutrouvelis, Thomas W. Sherson, Richard Heusdens +1
We propose a new robust distributed linearly constrained beamformer which utilizes a set of linear equality constraints to reduce the cross power spectral density matrix to a block…
Relaxed Binaural LCMV Beamforming
Andreas I. Koutrouvelis, Richard C. Hendriks, Richard Heusdens +1
In this paper we propose a new binaural beamforming technique which can be seen as a relaxation of the linearly constrained minimum variance (LCMV) framework. The proposed method c…
