New insights into the noise reduction Wiener filter
TL;DR: This paper studies the quantitative performance behavior of the Wiener filter in the context of noise reduction and shows that in the single-channel case the a posteriori signal-to-noise ratio (SNR) is greater than or equal to the a priori SNR (defined before theWiener filter), indicating that the Wieners filter is always able to achieve noise reduction.

GSVD-based optimal filtering for single and multimicrophone speech enhancement
Simon Doclo,Marc Moonen +1 more
TL;DR: Simulations show that the GSVD-based optimal filtering technique has a better performance than standard fixed and adaptive beamforming techniques for all reverberation times and that it is more robust to deviations from the nominal situation, as, e.g., encountered in uncalibrated microphone arrays.
Journal ArticleDOI
Frequency-domain criterion for the speech distortion weighted multichannel Wiener filter for robust noise reduction
TL;DR: It is shown that the SP-SDW-MWF is more robust against signal model errors than the GSC, and that the block-structured step size matrix gives rise to a faster convergence and a better tracking performance than the diagonal step size Matrix, only at a slightly higher computational cost.
Journal ArticleDOI
Design of broadband beamformers robust against gain and phase errors in the microphone array characteristics
Simon Doclo,Marc Moonen +1 more
TL;DR: Two design procedures for designing broadband beamformers with an arbitrary spatial directivity pattern are described, which are robust against gain and phase errors in the microphone array characteristics.
