Theoretical analysis of musical noise in Wiener filtering family via higher-order statistics
Recently, one of the authors has reported that the amount of generated musical noise is strongly correlated with higher-order statistics of the power spectra. On the basis of this...

Speech enhancement with masking properties in eigen-domain for colored noise
In this paper, we study speech enhancement in eigen-domain. In our previous work on audible noise reduction, we use masking properties of the human auditory system to define the ...

A single-channel noise reduction MVDR filter
Most existing approaches for single-channel noise reduction in the frequency domain via the short-time Fourier transform (STFT) assume that consecutive time-frames are uncorrelate...
