MultiFrequency MultiFunctions Wavelet
Song Guo-xiang · Mathematica Applicata · 2003
In this paper,multifrequency wavelets,vi a d irectional multiresolution analysis,generated by a single function is extended to wavelets generated by a finite number of functions.We derive necessary and s ufficient conditions for translates of φ 1,…,φ n,ψ 1,…,ψ n(2 j 1+j 2 -1) form a Riesz basis for V j (1) ,and some of the b asic mathematical structures.
