BLIND SIGNAL SEPARATING METHOD WHICH PREVENTS THE MIXING OF A SEPARATION FILTER WITH THE STATISTICAL PROPERTY

摘要

PURPOSE: A blind signal separating method and an apparatus implementing the same are provided to offer improved separation performance in various repercussion environments. ;CONSTITUTION: A blind signal separation apparatus changes a collected mix signal into the signal of a frequency domain(103). The apparatus calculates a separation filter matrix in each frequency(105). The apparatus calculates the reverse matrix of the separation filter matrix(107). The apparatus calculates a phase difference matrix from the reverse matrix(109). The apparatus estimates time delay parameters(111). The apparatus calculates mixing alignment(113). The apparatus performs the mixing alignment of a separation filter(115).;COPYRIGHT KIPO 2011
