基于已知的复合伸缩小波,本文给出一个构造对称反对称复合伸缩多小波的简单方法.这个方法可增加复合伸缩小波的数量,而且构造的多小波保持了原来小波的大部分性质.
Based on existing wavelets with composite dilations, we give a way of constructing symmetric or antisymmetric multiwavelets with composite dilations. This way can increase the amount of wavelets with composite dilations. Furthermore, new multiwavelets preserve the most properties of old wavelets.
