Robust, time-variant design of MVDR Beamformers

Authors: J. Bitzer, K.U. Simmer, M. Kallinger
Abstract: In this contribution, we show a noise estimation procedure in order to design an adaptive Minimum Variance Distortionless Response (MVDR)-Beamformer in the frequency domain. This new algo-rithm uses a multi-channel minimum statistic algorithm. This leads to a very robust implementation that outperform ideal Voice Activ-ity Detection (VAD) based algorithms in a non-stationary environ-ment.
