Improved methods for the design of 1-D and 2-D QMF banks
H. Xu, Wu-Sheng Lu, A. Antoniou · 2002
An iterative procedure proposed by Chen and Lee for the design of quadrature mirror filter (QMF) banks is extended to the design of two types of filter banks, i.e., l-D QMF banks with low reconstruction delay and 2-D nonseparable hexagonal QMF banks. Our simulations show that the extended methods are very efficient and yield good designs.>
