ABSTRACT:
Non-uniform filters are designed with a method which utilizes an orthogonal subbanding technique. A tiling representation of a signal is established. The signal is localized for both time and frequency using a mixed tiling representation of the signal. A prototype is then established using the joint time frequency representation of the signal. Lastly, non-uniform filters are developed utilizing the prototype.
