摘要：

dPulse signals possess instability characteristic caused by the experiment data through the Chinese pulse collecting system. It's difficult to pick up the feawres from the Pulse signals submerged by the noises. In order to resolve this question. we adopt the method of wavelet transform de-noising processing the pulse signal. Due to collect the pulse signal, it contain complicated signal. This paper studied many kinds of methods to remove noise from the pulse signal. such as wavelet multi-resolution analysis, inulti-layer threshold selection. polynomial curvre fitting etc. The simulated result shows the different de-noising methods process the effect of the pulse signal.
