System for Recognition of Chinese Medical Pulse Signal Based on Wavelet Analysis and Back Propagation Neural Network

Presently the system for recognition of Chinese medical pulse condition mainly aims at single pulse signal; the investigation of compound pulse signal is less. Article mainly researches single pulse signal and compound pulse signal. Firstly, we use wavelet analysis to extract character of pulse signal. Secondly, we make use of the nerve network to recognize. It constructs a considerably practical system for recognition of Chinese medical pulse signal based on wavelet analysis. Not only does the system own a good identify rate to single pulse condition, but also it can be more accurately to classify compound pulse condition. The experiment of many samples proves that the method has many advantages, foe example: the recognition rate is high and the speed is fast.
