Abstract :
A simple and efficient algorithm to design M-band perfect reconstruction (PR) quadrature mirror filter (QMF) banks is presented. The originality of our approach is that the design does not rely on a computationally intensive, nonlinear optimization method but rather on an iterative least squares method. The algorithm is simple to implement and rapidly converging. Design examples and a MATLAB program implementing the proposed algorithm are included
