Abstract: This paper presents a simple and efficient iterative technique for the design of cosine modulated pseudo quadrature mirror filter (QMF) banks. In the proposed algorithm, cutoff frequency is optimized to satisfy a new perfect reconstruction condition at frequency (ω = π/2M). Adjustable window functions are used to design the prototype filter cosine modulated pseudo QMF banks. When compared to other existing techniques, the proposed algorithm significantly reduces amplitude distortion, number of iterations, aliasing distortion, and computation time. Several design examples are included to illustrate the proposed algorithm and its improved performances over other exiting methods. Copyright 2009 ACM.
