本文介绍正交多小波、双正交多小波、半正交多小波的构造方法，以及多小波在信号处理方面的应用。
The main purpose of this paper is to introduce the construction of orthogonal, biorthogonal and semi orthogonal multiwavelet and the application of multiwavelet to signal processing.
对一般的双正交多小波系统，给出了阶平衡的较为简单的定义，并将预滤波理论引入双正交多小波滤波器组。
For common biorthogonal multi-wavelets system, a simple definition of balancing of order is proposed, and the prefilter theory is introduced to biorthogonal multi-filter Banks.
