Multirate and Filterbanks

Paper abstract
A method is proposed to solve the unconstrained optimization problem related to the design of perfect reconstruction biorthogonal modulated filter banks. The basic idea is to take advantage of some attractive properties of the parametrization of the underlying lifting scheme-based structure. This approach allows the design of prototypes with thousands of coefficients. Nearly optimal results are presented for two different optimization criteria.
