Beamforming Microphone Arrays for Speech Acquisition in Noisy Enviroments

Autoren: S. Fischer, K.U. Simmer
Kurzfassung: The transfer function in the look-direction is an adaptive Wiener-Filter which is estimated by using the short-time Fourier transform and the Nuttall/Carter method for spectrum estimation. The experimental results demonstrate that the proposed method works well for a large range of reverberation times and is therefore able to operate independently of the correlation properties of the noise field.
