Orthonormal subband coder design using polynomial eigenvalue decomposition

Abstract

We consider the design of M-channel orthonormal filter banks using polynomial matrix EVD techniques. Modifications are proposed to a time-domain, polynomial EVD technique, known as SBR2, which enables it to be applied effectively to the task of FIR paraunitary filter bank design for use in subband coding. This algorithm is compared to a well-known benchmark… (More)
