Abstract(in English) | Most of the existing algorithms in the blind source separation are confronted with the learning step-size problems. In this paper, we propose to break down the demixing matrix into row vector space. From the row vector viewpoint, a variable step (VS) algorithm for the blind source separation problem has been proposed. Instead of using a constant step-size, the VS learning algorithm adaptively changes the learning step-size of each row vector according to the convergence behaviors of its corresponding row vector. Out simulation results showed that the new VS learning algorithm outperforms the conventional algorithms. |
