Wavelet tight frames in Walsh analysis
Abstract. We describe two type of wavelet tight frames associated with the generalized Walsh functions: (1) Parseval frames for \(L^2\)-spaces on Vilenkin groups, (2) finite tight frames for the space \(\ell^2({\mathbb Z}_N)\). In particular cases these tight frames coincide with orthogonal wavelet bases associated with the classical Walsh functions.
