To provide a signal separating method capable of correctly associating an ID even if parameter information or an arriving direction changes without requiring parameter information, and capable of real-time display without requiring a storage device having a large storage capacity, and to provide a signal separating device using the method.
In the signal separating method, an independent component analysis is used to separate a source signal obtained from an observation value received by mixing the source signals from a plurality of independent transmission sources. This method has a step of standardizing each column of an etimatedly mixed matrix obtained by the independent component analysis, and calculating a standardized column vector.
