Recent Advances and New Design Method in Nonuniform Filter Banks

摘要：

This paper mainly presents some recent advances in designing nonuniform filter banks (NUFBs), including direct and indirect methods, along with the detailed review on the typical design methods. Starting with the description of the motivations behind using NUFBs in real applications, we identify some problems existing in the current work. As a new contribution, we then propose a simple design method of near perfect reconstruction (NPR) NUFBs with a linear phase (LP) property called partial cosine modulation. Here we design the first and last analysis/synthesis filters separately, while obtaining the others via cosine modulation of several prototype filters. A design example is given to demonstrate the effectiveness and simplicity of this approach.
