| The aim of this paper is to derive stable generalized sampling in a shift-invariant space with l stable generators. This is done in the light of the theory of frames in the product Hilbert space L2_l(0, 1) := L2(0, 1)×. . .×L2(0, 1) (l times). The generalized samples are expressed as the frame coefficients of an appropriate function in L2_l(0, 1) with respect to some particular frame in L2_l(0, 1). Since any multiply stable generated shift-invariant space is the image of L2_l(0, 1) by means of a bounded invertible operator, the generalized sampling is obtained from some dual frame expansions in L2_l(0, 1). An example in the setting of the Hermite cubic splines is exhibited. | |
