这是一个脉搏信号处理的代码，采用的小波分析，还做脉搏信号识别，对于学习信号识别和分类的人很有帮助(This is a pulse signal processing code, small wave analysis, and pulse signal identification, which is helpful for learning signal identification and classification)

能进行脉搏波的波峰波谷识别，还有一些基线漂移的处理(It can recognize the peak and valley of pulse wave, and process some baseline drift.)
