Abstract
We present a frequency-domain method of noisy convolutive source separation, where we extends the SEONS algorithm [2] that jointly exploits the nonstationarity and temporal structure of sources. Thus, the method is called F-SEONS, implying Frequency-domain SEONS. Unlike most of existing methods of convolutive source separation, we consider the case of noisy data and show that our F-SEONS algorithm identify multivariate FIR channels in a robust way. In addition, we employ an H?닞 filtering method in order to further suppress the sensor noise. Numerical experiments with comparing to other methods, confirm the high performance of our proposed method. © 2005 IEEE.
