Parameter Estimation of 1/f-Type Fractal Signal Using Least Square Method
1/f类分形信号的最小二乘法参数估计

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 fra...
