基于小波变换的有限长度信号的分解与重构算法

Decomposition and Reconstruction Algorithm of Finite Length Signal Based on Wavelet Transform

针对Ｍａｌａｔ的小波分解与重构的塔式算法，具体地对有限长度信号提供了一种小波分解与重构的算法，该算法仅利用了有限个小波基，无需对信号进行周期延拓。

A wavelet transform algorithm of finite signals associated with Mallat's wavelet algorithm is proposed,which only use finite wavelet bases without periodically extension signals,so that the signals can be reconstructed perfectly.
