Compactly supported multi-wavelets
Wojciech Banaś · Opuscula Mathematica · 2012
In this paper we show some construction of compactly supported multi-wavelets in L 2 (R d ), d ≥ 2 which is based on the one-dimensional case, when d = 1.We also demonstrate that some methods, which are useful in the construction of wavelets with a compact support at d = 1, can be adapted to higher-dimensional cases if A ∈ M d×d (Z) is an expansive matrix of a special form.
