摘要
小波变换是近年来兴起的一种时频域信号分析理论，是信号分析处理的一种强有力的新工具。文中根据小波变换的特点，在Ｍａｌａｔ“二通道”多分辨分析的基础上，讨论分析了信号的多通道多分辨分析的理论和实现算法。给出了实验模拟结果。
Wavelet transform,especially the multiresolution representation is a very effective tool for analyzing the information contents of a signal.Based on Mallats multiresolution analysis,this paper discuses the theoretical analysis of M channel multiresolution signal decomposition,proposes a new algorithm for realizing the theory,studies the properties of an operator which approximates a signal at a given resolution,and describes experimental results.The results shows that the signals can be decomposed and reconstructed by M channel multiresolution representation.The algorithm is proved to be simple,reliable and very useful for signal processing.
