In this brief, we propose a new method to design pseudo-QMF prototypes to implement near perfect reconstruction (NPR) modulated filter banks. The proposed method is based on the eigenfilter approach, simple to implement, but nevertheless, very efficient in designing high attenuation filters. The method also allows to design complex coefficient prototypes that may be used to build nonuniform filter banks. Several examples of both uniform and nonuniform filter bank design are presented.

Abstract

In this brief, we propose a new method to design pseudo-QMF prototypes to implement near perfect reconstruction (NPR) modulated filter banks. The proposed method is based on the eigenfilter approach, simple to implement, but nevertheless, very efficient in designing high attenuation filters. The method also allows to design complex coefficient prototypes that may be used to build nonuniform filter banks. Several examples of both uniform and nonuniform filter bank design are presented.
