Generalized sampling theorems in multiresolution subspaces

In fact, with nonuniform sampling, oversampling, and reconstruction from local averages, we can guarantee compactly supported synthesizing functions. ...
All these problems are treated in a unified way using the perfect reconstruction (PR) filter bank theory. We give conditions for stable reconstructions in each of these cases. ...
So far, we considered -channel maximally decimated filter banks only (Fig. 1 is a Fig. 7 . Filter-bank interpretation of oversampling. special case with ). ...
