In the light of the stock exponential curve on the background of the noise, this paper gives a kind of effective method for the wavelet hard-threshold de-noising and singularity detection, selects the bi-orthogonal spline wavelet as the basic wavelet and utilizes the wavelet analysis to erase the interference of the signal noise, and connecting with the multi-scale analysis and the singularity detection, reveals the implied background of the stock exponential information.
