| Abstract(in English) | It is well known that KT method proposed by R. Kumaresan and W. Tufts is used as a popular frequency estimation method of the exponentially damped signal. It is based on linear backward-prediction method and singular value decomposition (SVD). However, it is difficult to estimate frequencies correctly by KT method in the case when the noise increases. In this paper, we propose a frequency estimation method to improve the performance of KT method when the noise increases. In our proposed method, we find the signal zero groups by calculating zeros with several different data record lengths based on the combination of forward-prediction and backward-prediction. The frequency components are calculated by the mean value of the zeros in signal zero groups. Simulation results are shown to confirm the effectiveness of the proposed method. |
