| Abstract(in English) | On the problem like underdetermind signal separation of speech signal mixtures, that is, separation of more sources than mixtures, we need to find a unique and practically useful solution after the linear system is identified. For this problem, the minimum l_1-norm solutions at each data point have been used in the previous studies, and a linear programming have been used usually to solve each subproblem. For large scale data like speech signals, we propose the method which can construct such minimum l_1-norm sequence effectivelly. |
