Abstract(in English) | High accuracy estimation of DOA with MUSIC method using microphone array is difficult due to noise and reverberation in office rooms. Therefore, various methods have been proposed to improve the estimation accuracy. We propose a new method using three preprocessor for received signal of microphone array to imrove the estimation accuracy. The first processor is to apply the adaptive filter to reduce room reverberation, the second and third processor utilizes the filter bank and the different frame length to improve accuracy of frequency transformation. It was shown that the proposed method improved the DOA estimation acucuracy in real environment. |
