| Abstract(in English) | In the acoustic echo cancellation(AEC), the step-size parameter of the adaptive filter must be varied according to the situations where a double talk and/or an echo path change occur. We propose an AEC using the sub-adaptive filter(Sub-ADF). AEC using the Sub-ADF can control the step-size parameter according to the situations. Moreover, the proposed AEC can realize superior convergence property to the conventional one even when the double talk and the echo path change simultaneously occur. Simulation results demonstrate that the proposed AEC can achieve higher ERLE and faster convergence than the conventional one. In addition, the additional computational complexity of the proposed method can be reduced by reducing the number of taps of the Sub-ADF. |
