frequency permutation
in [Matlab]

From: AB on 25 Feb 2010 09:39 Hi, Is there anybody could help me with this problem? I am working with source separation in frequency domain.What I'm doing is, I first transform the time domain mixtures into frequency domain using the STFT.Then do the separation. When I take inverse STFT, there must be permutation effect to the output. Therefore, I would like to know how can we efficiently measure the permutation. I know an easy way to do that in the simulation (such as comparing both separated bins and original bin signals at each sample) but wonder if there is a more systematic way? Thank you for any suggestion. AB
