Multisensor Signal Processing: Theory and Algorithms for Image -Based Rendering and Multichannel Sampling

Abstract

Finally, motivated by multichannel sampling applications, we consider hybrid filter banks consisting of fractional delay operators, analog analysis filters, slow A/D converters, digital expanders, and digital synthesis filters to approximate a fast A/D converter. The synthesis filters are to be designed to minimize the maximum gain of an induced error system. We show the equivalence of this system to a digital system, used to design the synthesis filters using control theory tools, including model-matching and linear matrix inequality. The designed system is robust against delay estimate errors.
