用自适应提升格式对信号精确重构(英文)

PERFECT RECONSTRUCTION WITH ADAPTIVE UPDATE-LIFTING SCHEMES

本文分析了几种自适应提升格式在信号精确重构中的应用 ,在其计算过程中 ,它们均无须考虑当前步骤之前的数据。并分析了它们的优缺点。最后 ,提出一种构造自适应提升格式的方法 ,通过计算表明 。

This paper treats several adaptive update\|lifting schemes for perfect reconstruction, which do not require bookkeeping in their calculations. In succession, we study their advantages and disadvantages more precisely. At last, we give a new method in choosing these adaptive update\|lifting filters, which is proved better than the method in .
