Abstract

The design of perfect reconstruction FIR multifilters is discussed in this paper. The Schur algorithm is applied to factorize the polyphase matrix of multifilters into lattice blocks. The multifilters are characterized by the chain parameters in each lattice block. The complete parameterization of paraunitary multifilters and a class of biorthogonal multifilters are derived. The parameterizations are minimal and result in simple design methods using unconstrained optimization
