Abstract

A genetic algorithm is presented for searching optimization parameters in the factorization matrices in linear-phase filter banks. The genetic algorithm is combined with the simplex algorithm to accelerate the design process. The newly algorithm alleviates the problem of being trapped in local minimums, as the initial parameters are selected by the genetic algorithm. Less human interactions are required in the design of filter banks, especially when impulse responses are long. The experimental results show that the proposed algorithm is robust in the optimization of the filter coefficients. Design results of filter banks with 8 channels are included.
