Performance comparison of two channel CMFB and QMF bank designed via ABC algorithm

In this study, Cosine Modulated Filter Bank design and Quadrature Mirror Filter Bank design are performed using prototype filter designed with Artificial Bee Colony Algorithm. The same design example parameters were used for both filter banks; the performances of the filter banks designed at different orders are compared in terms of stopband attenuation, mean square error, peak reconstruction error and computational time.
