| Abstract(in English) | A method to estimate the number of sources in the blind source separation problem is proposed. Assuming a time-frequency independence of sources, the number of sources is estimated through the quotient of complex valued time-frequency information of two observed signals. Mathematical formulation of this method is discussed. |
