Abstract
In this paper, we introduce the notion of generalized multiresolution structure (GMS) in the setting of reducing subspaces of L2(ℝd). For a general expansive matrix, we obtain a necessary and sufficient condition for GMS, and prove the existence of GMS in a reducing subspace. Using GMS, we obtain a pyramid decomposition and a frame-like expansion for signals in reducing subspaces.
