PERMUTATION/SCALE PROBLEM SOLVING APPARATOUS AND METHOD FOR BLIND SIGNAL SEPARATION

摘要

Disclosed is a permutation/scale problem solving apparatus and a method for blind signal separation. According to the present invention, the permutation/scale problem solving apparatus includes a frequency element sum part adding a (2n-1)^th frequency element adjacent to different frequency output signals and a 2n^th frequency element together; a frequency element resum part again adding the (2n-1)^th frequency element summed by the frequency element sum part and the 2n^th frequency element together; a blind signal separation part performing a blind signal separate process based on each resumed signal by the frequency element resum part and a summed signal summed by the frequency element sum part and the original output signal (here, n is a natural number).
