摘要
As for this application, it regards the manner which decides at least one update being completed filter coefficient of the adaptation filter (22) which it can be adapted by LMS algorithm. With the said manner, filter coefficient of the 1st whitening filter (25 ') is decided, filter coefficient of the especially LPC whitening filter. The 1st whitening filter (25 ') generates the filtering being completed signal. Normalization value is decided on the basis of the value to which one or more which is obtained with the process which decides the filter coefficient of the 1st whitening filter (25 ') was calculated. It is related normalization value, with the energy of the filtering being completed signal. Depending on the filtering being completed signal and normalization value, the adaptation filter (22) one update being completed filter coefficient is decided at least. It is desirable, all the filter coefficients of the adaptation filter (22) concerning update filter coefficient is decided the. Choice figure Drawing 8
