  • Method of estimating parameters of time series data using fourier transform
    Publication number: 20060047452
    Abstract: A method of estimating parameters of time series data using a Fourier transform is disclosed. The parameter estimation method of the present invention can directly estimate modes and parameters, indicating the characteristics of a dynamic system, on the basis of the Fourier transform of the time series data. Accordingly, the present invention is advantageous in that it can estimate parameters of the system through a single Fourier transform without repeatedly calculating a Fourier transform, thus shortening the time required to estimate the parameters.
