一种新的实时小波分析

A New Method of Real Time Wavelet Analysis

叙述了多分辨分析的定义后 ,分析了Mallat塔式算法的特点及不能用于实时分析的不足。针对Mallat算法的结构及小波函数有限支撑的特点 ,提出了对Mallat算法进行改进的垒墙式算法。新算法的信号处理不再是自底至顶进行 ,而是按信号顺序进行 ,从而可实现信号的实时处理。

After described the define of multi-resolution analysi s,the characteristics of Mallat algorithm and its shortage are discussed.Conside ring the structure of the Mallat algorithm and the support of wavelet function a re limited,the bricklaying algorithm is presented.The orientation of signal proc essing in the new algorithm isn't from the bottom to top,but in order of time in the mass.So it can be used in the real time signal process.
