Symmetrie delay factorization: A generalized theory for paraunitary filter banks

Abstract

The Symmetric Delay Factorization (SDF) is introduced in [1] for synthesizing linear phase paraunitary filter banks and is applied successfully in [2] for designing Time Varying Filter Banks (TVFB). This paper describes a minimal and complete generalized symmetric delay factorization theory valid for a larger class of paraunitary filter banks. The approach… (More)
