Abstract
In this paper, we propose a simple method for designing linear-phase (LP) nonuniform filter banks (NUFBs) with integer decimation factors. The NUFBs are constructed in a direct structure. We derive a design criterion for the NUFB. With this criterion, the NUFBs can be designed simply and efficiently. By using the proposed method, near-perfect-reconstruction LP NUFBs with high stopband attenuation are obtained.
