摘要
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.
