| Abstract(in English) | We propose a new multi-channel acoustic echo cancellation algorithm based on independent component analysis (ICA) with a separation matrix constraint. This algorithm is robust against echo path changing it can estimate the echo path at a double-talk interval. ICA-based echo cancellation achieves the echo reduction by separating the near-end signals using ICA based on assumption that the near-end signal and the far-end signals are mutually independent. To reduce echo components robustly against far-end echo path changing, the proposed method is learned with the specific constraint to the separation matrix. Also, it can estimate the echo path not only at a single-talk interval but also double-talk interval becase of utilizing for ICA. Furthermore, we can simplify the scalling and the permutation problem in ICA by constraint of the separation matrix and the multiple-input single-output structure. The two chanel and three channel experiments reveal that the algorithm results in higher stability against the far-end echo path changing and the double-talk interval. |
