摘要：
The independent component analysis (ICA) in the frequency domain is a method to deal with a blind signal separation problem in which propagation time delays are included in the mixing process of signals. We propose an extended method of the frequency-domain ICA accompanying the estimation of the relative propagation time delays and the propagation coefficient ratios. The effectiveness of the proposed method has been confirmed by simulation experiments. In addition, the sound localization by the proposed method is further discussed.
