|Abstract:||An efficient algorithm is presented in this paper to design lattice-type perfect reconstruction quadrature mirror filters (PR-QMF). Our proposed iterative algorithm design the lattice coefficients of the filter bank directly, with flexible control of the filters' stop-band ripple profiles. Typically, only a few iterations of our algorithm is needed to converge to an optimal solution in the weighted minimax sense. A procedure to obtain the lattice coefficients of PR-QMF banks yielding near linear phase filters is presented.|
