  • In this work, we provide polyphase, modulation, and frame theoretical analyses of a filter bank on a discrete abelian group. Thus, multi-dimensional or cyclic filter banks as well as filter banks for signals in l(2 )(Z(d) x Z(s)) or l(2) (Z(r) x Z(s)) spaces are studied in a unified way. We obtain perfect reconstruction conditions and the corresponding frame bounds in this particular context.
