Abstract :
The structure of linear-phase paraunitary filter banks with arbitrary number of channels is discussed. Minimal factorization and parametrization of linear-phase paraunitary filter banks with length MN filters is derived. Parametrization of pairwise mirror image filter banks is discussed and a design example is presented
