Abstract This paper studies the design and optimization of LPPR-FIR filter banks by liftingscheme. It can be commutated into a quadratic optimization problem. Then, lifting scheme is generalized to the case of M-band perfect-reconstruction (PR) FIR filter banks. Last, some examples will be given to demonstrate how to construct LPPR-FIR filter banks.

Key words： Lifting scheme M-band filter banks Perfect reconstruction Linear phase
