Abstract

In this research, we propose a direct design method of nonuniform filter banks (NUFBs). This method is based on frequency domain constraints to eliminate the amplitude and the aliasing distortions. Both NUFBs with integer and rational sampling factors can be designed with common procedure. Here, we also consider the design method which requires only to solve linear equations iteratively. In our proposed method, least square error of the perfect reconstruction (PR) constraints is minimized without using the nonlinear programing technique.
