Design of over sampled perfect reconstruction FIR filter banks
In this paper, we propose the design method for over sampled filter banks which satisfy the perfect reconstruction and linear phase properties. Moreover, we consider the design methods for both orthogonal and biorthogonal ones. We first derive the conditions of perfect reconstruction and linear phase for both biorthogonal and orthogonal filter banks. Then, we present the design methods for both cases. Finally some design examples are shown.
