Frequency-domain implementation of a time-domain blind separation algorithm for convolutive mixtures
Author(s): Masashi Ohata, Kiyotoshi Matsuoka
Abstract
This paper proposes a way to implement a time-domain blind separation algorithm
for convolutive mixtures of source signals. The approach provides another
form of the algorithm by discrete Fourier transform and has the posibility
of designing a separating filter in the frequency domain, without bothering
about the permutation problem inherent in frequeny-domain blind separation
approach.
This paper also shows a technique to improve separation performance in the frequency
domain.
The validity of our approach was demonstrated by performing an experiment on
separation for convolutive mixtures of two speeches. |
