Abstract
According to characteristics of Wavelet Transform and requirements of signals eliminate noise,this paper researches control noises of signals and remove noises from the steady and unsteady signals with the technique of wavelet.It expounds the basic theory and method of removing noises from signals with wavelet transform,and then uses Matlab to realize simulation of wavelet non-noising by programming.The experiments show that satisfactory results can be available through eliminating noise based on wavelet analysis.
