| Abstract(in English) | An input signal when the howling occurs consists of feedback signal and speech signal. Removal of howling signal was performed by means of adaptive notch filter,but speech signal contained in the input signal has been used on the assumption that wideband uncorrelated signal. However, speech signal is a colored signal with a high correlation,the power of the speech signal had to be small enough in removing the howling by the single adaptive notch filter. In this paper we propose a real time howling Canceller that independent on the size of speech signal. The system configuration of the proposed method divided into howling removal unit and howling frequency estimation unit. The howling frequency estimation unit have cascaded adaptive notch filter that howling estimated a filter to remove the speech signal. The howling removal unit,for removing only the howling signal by a notch filter for removing a single frequency that is estimated. Simulation results present the effectiveness of the proposed method |
