Abstract :
A new method of denoising with the sym4 wavelet under the soft threshold rule is presented to remove noise in a digital signal spectrum-coding transmitting system. From the simulation of the de-noising process, a conclusion can be drawn that this method is effective in real time de-noising in a digital signal spectrum-coding transmitting system
