| Abstract(in English) | In actual system identification, the power spectral density of input signal is localized in a somewhat frequency range. It causes an ill-conditioned situation in system identification. In this paper, the impulse response identification algorithm that could work well even in the ill-conditioned situation is proposed. Firstly, we employ the wavelet packets transform on input / output signals to recursively estimate the impulse response in wavelet transform domain. Next, we stabilize the estimate by selection of the packets. Finally, the estimated impulse response is given as an inverse wavelet transform of it. The effectiveness of proposed methods is illustrated through numerical simmulations. |
