小波变换在微弱生命信号处理中的应用

摘要

小波变换是时间和频率的局部变换,它在多领域的研究都取得了有科学意义和应用价值的成果.本文对小波变换作了简要介绍,对小波变换在微弱生命信号中的应用进行了初步探讨.%Wavelet transform is a partial transform in time and frequency. The research of wavelel transform has acquired scientific achievements.This paper briefly describes wavelet transform and discusses its application in faint signal of life.
