On Characterization of Nonuniform Tight Wavelet Frames on Local Fields
Owais Ahmad Neyaz A. Sheikh, Neyaz A. Sheikh · Analysis in Theory and Applications · 2018
In this article, we introduce a notion of nonuniform wavelet frames on local fields of positive characteristic. Furthermore, we gave a complete characterization of tight nonuniform wavelet frames on local fields of positive characteristic via Fourier transform. Our results also hold for the Cantor dyadic group and the Vilenkin groups as they are local fields of positive characteristic.
