APPLICATION OF WAVELET TRANSFORM IN SIGNAL DE-NOISING AND REALIZATION WITH MATLAB
Jiang Yuan-zhi · Journal of Beijing Technology and Business University · 2009
In view of the noise pollution in signal detection,this paper deals with the general theory of wavelet transform,the application of wavelet transform in signal De-noisinng as well as the analysis of the characteristics of noise-polluted signal.At last,the Matlab is used to be carried out the simulation where the different wavelet and different threshold of the same wavelet for signal De-noising are applied,simulation shows that the wavelet transform can achieve excellent results in signal De-noising.
