从尺度函数出发,利用框架多分辨分析(FMRA),借助于滤波器,在L2(Rd)中构造了一对以整系数可逆矩阵A为伸缩因子的对偶框架小波,并找到了正交Parseval框架小波滤波器满足的一个充分条件.
Motivated by the notion of frame multiresolution analysis,with the help of filters,a pair of dual frame wavelets in L2(Rd) with dilated matrix A which entries are all integers from a scaling function are constructed.Furthermore,a sufficient condition satisfied by the filters of orthogonal Parseval frame wavelet is shown.
