Abstract :
We present a frequency 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 an extended LP method. Performance of the proposed method is evaluated by computer simulation, and the lower variance of parameter estimation error is estimated by using the Cramer-Rao bound
