小波分析在信号处理中的应用研究

摘要

Wavelet analysis is the inheritance and development of the Fourier transform Firstly, the paper introduces the practical background of wavelet theoky and the basic principles of the wavelet transform, especially the multi-scale analysis theory, Finally, through the experiment, a fractional signal multiscale wavelet transform is realized.%小波分析是对傅里叶变换的继承和发展,首先介绍了小波理论产生的实际背景和小波变换的基本原理,特别是多尺度分析理论.最后,通过实验实现了分形信号的多尺度连续小波变换.
