Strang-Fix 条件; 超函数; 逼近阶
该文把M进制尺度函数的逼近阶与超函数联系起来, 证明超函数可以显式构造出来, 并给出利用Strang-Fix条件构造超函数的一般方法, 就M=2情形, 对由G.Strang和V.Strela提供的例子, 利用文中算法, 得到它的超函数和一些新的性质。

Permutation; non-separable wavelets; conjugate quadrature filter
After some permutation of conjugate quadrature filter,, new conjugate quadrature filters can be derived., In terms of this permutation,, an approach is developed for constructing compactly supported bivariate orthogonal wavelets from univariate orthogonal wavelets., Non-separable orthogonal wavelets can be achieved., To demonstrate this method,, an example is given.,

Nonlinear Fourier atoms; Kadec type 1/4-theorem; Weyl-Heisenberg frame. AMS Subject Classification: 42C05, 65R10
In this paper,, we study the stability of two kinds of frames generated by nonlinear Fourier atoms., The first result is the Kadec type 1/, 4-theorem., The second states that thenonlinear windowed Fourier atoms form a frame of L2(, R), .,
