摘要
本文综述了小波分析这一前沿领域的发展现状 ,介绍了小波变换及其Mallat快速小波算法 ,对比分析了小波变换与短时傅里叶变换之间的差异 ,指出这种基于多分辨方法的小波变换特别适合于非平稳信号的分析与处理 。
In this paper,we first summarize the development of the wavelet theory.We introduce the wavelet transform and Mallat fast algorithm,and briefly compare the wavelet transform with the more classical sthort time Fourier transform approach to signal analysis.This paper shows that the wavelet transform on the multiresolution approach is particularly suitable for the analysis of nonstationary signals.
