  • A novel method to estimate the parameters of 1/f-type fractal signal is proposed according to characteristics of the wavelet coefficient variance versus scale of 1/f-type fractal signal in white noise, and namely, after the wavelet coefficient variance is simply transformed, the parameter estimation of 1/f-type fractal signal is according with parameter estimation conditions of least square method. The simulation experiment results demonstrate that, this method can effectively estimate parameters of 1/f-type fractal signal such as and 2 etc.to extract them from additive white noise.
