In this paper, methods for processing arbitrary-length input signals with MDFT filter banks will be presented. The MDFT filter bank can be regarded as the most general type of a special class of filter banks. These filter banks have linear phase analysis filters, but different centers of symmetry due to subsampling with and without a phase shift. Already known extension methods cannot be applied to these filter banks in their original form. We first discuss the symmetric extension for two special input signal lengths. These cases are then incorporated in the general solution for arbitrary-length input signals.
