Fast Filter Bank Design (ffbd)

The goal here is to design M analysis and synthesis FIR filters based on the method proposed in [1] so that the perfect reconstruction conditions are satisfied (or almost satisfied) and the energy in the analysis and synthesis filters' stopband areas is minimized (strong stopband attenuation). The algorithm can design both uniform (critically/over sampled) and non-uniform (compatible/incompatible) filter banks.
The method is described in the following paper:
