| Abstract(in English) | In this paper, we present a new parameter estimation method of acoustic signals based on the sinusoidal additive synthesis model. In the proposed method, frequencies both in signal and noise are estimated with several delay times by using a linear prediction(LP)model, when assuming that the signal is stationary and noise is unstationary in short record length. And frequencies in the signal are extracted according to their dependence upon different delay times. The amplitude and phase estimation of the proposed method is based on the least square method. The parameter estimation can be accomplished with short record length even in the case where the number of frequency components in the signal is unknown. And it is capable of estimating the parameters of a signal in the presence of noise. Furthermore, the proposed method estimates the parameters with less computation and high estimation accuracy. Simulation results are provided to confirm the effectiveness of the proposed method. The comparison of estimation error between the proposed method and the analysis by synthesis(ABS)method is shown. |
