从L2(Rd)构建琴小波框架的一般方法(即延拓原理)出发,利用函数的周期化过程,给出了L2([0,1]d)上二类紧小波框架的构造方法…
In this paper, the authors present a method to construct a class of tight wavelet frames for L2([0,1]d) by means of function periodization from the general method construct- ing tight wavlet frames for nL2(Rd)-- the Extension Principles.
