Abstract
A method for separating a blind signal includes: converting mixed signals of a time domain collected by using a plurality of sensors into mixed signals of a frequency domain; calculating a separation filter from the mixed signals which have been converted into those of the frequency domain; calculating an inverse filter of the separation filter; calculating the difference in phase between the respective sensors from the calculated inverse filter; permutation-sorting the separation filter by using the calculated phase difference; and separating the mixed signals of the frequency domain by using the permutation-sorted separation filter.
