Abstract

In the paper, an algorithm based on Dual-Tree Complex Wavelet Transform is proposed for process denoising. Use the variance of the wavelet coefficients at different scales to estimate the parameters of process. Adopting Maximum a Posteriori estimator estimates the wavelet coefficients of process. The simulation results show that the method is effective. And comparing with other methods this method doesn’t need to know the statistical characteristic of the added white noise and the parameters of the process.
