| Abstract(in English) | We present a new learning algorithm for solving a least-squares joint diagonalization problem at every frequency bin in convolutive frequency-domain blind source separation. Conventional algorithm requires computational burden for computing inverse matrix at every frequency bin. The proposed algorithm employs the matrix inversion lemma. It is useful to recursively estimate un-mixed matrix without being affected by initializing the algorithm. The performance of the algorithm will be evaluated in real reverberant environments. |
