  In this paper a two channel paraunitary filter bank is proposed, which is
based on linear canonical transform, instead of discrete Fourier transform.
Input-output relation for such a filter bank are derived in terms of polyphase
matrices and modulation matrices. It is shown that like conventional filter
banks, the LCT based paraunitary filter banks need only one filter to be
designed and rest of the filters can be obtained from it. It is also shown that
LCT based paraunitary filter banks can be designed by using conventional
power-symmetric filter design in Fourier domain.
