Abstract

This paper proposes new building blocks for the lattice structure of oversampled linear-phase perfect reconstruction filter banks (OLPPRFBs). The structure is an extended version of higher-order feasible building blocks for critically sampled LPPRFBs. It uses fewer number of building blocks and design parameters than those of traditional OLPPRFBs, whereas frequency characteristics of the new OLPPRFBs are comparable to those of traditional one. Furthermore, the building block structures for arbitrary number of channels and downsampling factors are presented.
