Hendriks, R.C. (author), Heusdens, R. (author), Kjems, U. (author), Jensen, J. (author)In this letter we present discrete Fourier transform (DFT) domain minimum mean-squared error (MMSE) estimators for multichannel noise reduction. The estimators are derived assuming that the clean speech magnitude DFT coefficients are generalized-Gamma distributed. We show that for Gaussian distributed noise DFT coefficients, the optimal...journal article 2009
