Abstract:
A frequency estimation method was presented for weak sinusoidal signal embedded in chaotic‘noise’based on parameter variation chaotic synchronization which one filtered driving variable isused to drive response chaotic system.Because the error data series between drive and response signal has only little chaotic interference and has the sinusoidal signal.Usingthecrossspectral MUSIC method to estimate the sinusoidal frequency in the error data.The method issuit for the situation where noises are mixture of strong chaotic noise and white noise.
Key words: chaotic synchronization, parameter variation, cross-spectral MUSIC method, frequency estimation
