| Abstract(in English) | Discrete Fourier Transform (DFT) method and Linear Predictive (LP) method are generally used for frequency estimation. However it is very difficult to apply these methods for frequencies that vary momently. The purpose of this paper is to obtain the accurate estimation method for near-by frequencies that can't be estimated by conventional methods from short time data. The proposed method utilizes that correlation for nonorthogonal frequencies vary with time. The merit of the method is to be able to estimate frequencies and ampritudes more accurately compared to conventional methods. Simulation results confirm the validity of the method. |
