This paper mainly introduces a new method to estimate the coefficients of the mathematic model. Firstly we do the pretreatment of the experimental data by means of the discrete wavelet to get rid of the noise. Then the model coefficients can be estimated by the treated data more properly than by the original data. We consider the problem of estimating the coefficients of SELF-SReM as an example to explain this new method.
