| Abstract(in English) | The pole estimation method is actively researched to the AR system. One example includes the analysis of the FID signal in the NMR spectroscopy etc.Something that the linear predictive method is used is the main method of PEM. This method estimates poles of unknown system from the requested AR coefficient by the factorization by the linear predictive method for the AR coefficient. However, even when the error of mean square of the signal is small, the estimation accuracy of the poles is not necessarily high. Therefore, even if an degree of unknown system is already-known, accurate pole estimation is difficult. It proposes the precision pole estimation method by estimates poles of unknown system by excessively high-order estimation system compared with unknown system , selection of an best combination from estimated poles. The pole estimatin accuracy improved by using the proposal method by about 42dB compared with the conventinal method. |
