摘要
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。在应用过程中 ,由于多小波的特殊性 ,需要对原始信号的采样数据作处理 ,称为预处理。预处理在多小波的应用上是很关键的一步。它与选取的多小波基有关 。
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. In application, because of the particularity of multiwavelet it's necessary to deal with the sampling data of original signal, namely, the preprocessing procedure. Preprocessing procedure is the important step in application of the multiwavelet. It's relative to the choice of the multiwavelet basis, There has the corresponding preprocessing method based on the different multiwavelet basis.
