The goal is to design M analysis and synthesis FIR filters so that the analysis filters satisfy some frequency specifications and the filter bank(almost) meets the perfect reconstruction (PR) conditions. Both goals are achieved by minimizing the following performance index:
J=w1*(PR error)+w2*(Frequency Specification error)
where w1 and w2 are optional weights
The algorithm can design both uniform (critically/over sampled) and non-uniform filter banks.
