PROCESSOR FOR SEPARATING BLIND SIGNAL

PROBLEM TO BE SOLVED: To provide a blind signal separation processor capable of separating an original signal with a blind from a signal (signal such as sound, an image and a radio wave) in a real environment where background noise exists and is convolutionally mixed. SOLUTION: This blind signal separation processor in which a plurality of observing means observe signals to be separated outputted from a plurality of signal sources and the original signal is separated by using only the observed signals, comprises a plurality of sensors 1 for detecting the signals to be separated, a signal to be separated storing part 2 for storing the signals to be separated detected by each of the sensors, a signal processing part 3 for extracting the signals from the signal to be separated storing part and performing processing that separates the signal to be separated into signals of respective signal sources, and a separated signal storing part 8 for storing the separated signals separated by the signal processing part 3.
