| Abstract(in English) | In recent years there are demands for techniques that would be able to recieve desired sound in environmental noise when broadcasting programs. We propose a new sound receiving method for a 2-inputs and 2-outputs system using the Blind Source Separation, when desired sound and environmental noise exist in front of the microphones on a straight line. Under the condition that the source signals are mutually independent and the measured signals are linear combination of two signals, we estimate mixing matrix coefficients by minimizing the cross-correlation of 2-outputs signals. through computer simulation and experiments in an anechoic room, we confirmed that our method is promising. |
