A simple design method for near-perfect-reconstruction nonuniform filter banks
Jianlin Li, Truong Q. Nguyen, S. Tantaratana · IEEE Transactions on Signal Processing · 1997
In this correspondence, we propose a simple design method for nonuniform integer-decimated filter banks based on a uniform cosine-modulated filter bank. The resulting distortion and aliasing are comparable to the stopband attenuation of the prototype filter. Examples are given to demonstrate the proposed method.
