Design of Cosine Modulated Filter Bank Using Unconstrained Optimization Technique
Shaheen  | Dinesh K. Dhaka
Abstract: This paper proposes a unique method for designing of cosine modulated-QMF bank using unconstrained optimization technique. Objective function of this QMF bank is a quadratic equation form by combining the total pass band error, mean square error of band pass and stop band. We are using the unconstrained optimization method for minimizing the objective function. Result shows that the performance is better than the existing method.
