利用Fourier变换和周期化技巧,给出Fourier域上L^2(R^d,C^L)中约化子空间上的超仿射小波对偶框架的一个充分条件,从而将L^2(R^d)中约化子空间上的结果推广到向量值空间L^2(R^d,C^L)的约化子空间上.
By using the Fourier transform and periodic technique,the author gave a sufficient condition for the super affine wavelet dual frame in the Fourier-domain under the setting of reducing subspaces of L^2(R^d,C^L),so that the result in the reducing subspaces of L^2(R^d)was generalized to the reducing subspaces of vector-value space L^2(R^d,C^L).
