| Abstract(in English) | There are many studies to eliminate echo and to estimate a radiated signal. In the case of musical instruments, whose sound varies for each play and also is far from impulse. In addition, the size and the radiation characteristic of musical instrument are very different from usual acoustic transducer, such as a loudspeaker. Due to these difficulties, it is impossible to estimate original sound of musical instrument by means of the conventional techniques. This paper presents a method which consists of invers filter and cepstrum analysis to estimate a original signal. The results of simulation show the effectiveness of the proposed method, its both ERLE and S/N increase by 7.47dB. |
