Abstract :
Some results for multidimensional m-band bi-orthogonal filter banks are presented. In the first part of the paper the authors introduce the ladder structure as a method for the design and implementation of the aforementioned filter banks. The second part of the paper focuses upon enforcing linear phase (LP) conditions in the context of ladder structures. The formulation of the LP conditions is done with the help of an algebraically oriented method for describing multidimensional filter banks. It is shown that in this notation, ladder structures allow a natural formulation of LP conditions
