Abstract :
The paper presents a new method based on the wavelet theory and fuzzy recognition technology for the first time to analyze body dynamic blood pressure signal. The method of edge extending is adopted in order to eliminate edge effect in signal pre-processing; the ability of signal characters extracting is enhanced greatly because of application of DWT and CWT; the fuzzy recognition technology introduced by the paper achieves accurate recognition signal. It is tested the method is effective and practical.
