On the Theory and Design of a Class of PR Uniform and Recombination Nonuniform Causal-Stable IIR Cosine Modulated Filter Banks

摘要

This paper studies the theory and design of a class of perfect reconstruction (PR) uniform causal-stable infinite-impulse response (IIR) cosine modulated filter banks (CMFBs). The design approach is also applicable to the design of PR recombination
