Abstract

In this paper, a new design algorithm is presented for paraunitary filter banks with extended filter length. Equal-length filter banks are designed where the filter length is not restricted to integral multiples of the number of channels. Filter banks with unequal length are also studied. In the new algorithm, the filter lengths are iteratively reduced through a cascade of lattice structures and delay chains. Design examples of 5 channels with different filter lengths and stop band attenuations are presented.
