Abstract(in English) | The spatial mixture problem is considered. The estimation of the number of sources and source separation are given. We assume that the sources satisfy some independent condition in a time-frequency space. The number of sources is estimated by using the quotient of complex valued time-frequency information of the two observed signals. Then, we can separate the sources by sufficiently many observed signals. In this report, applications of this method are given. |
