Abstract :
In this work, a new design method of M-channel linear-phase paraunitary filter banks (LPPUFB) is proposed for odd M with a cascade structure. The conventional cascade structure has a problem that one of the filters is restricted to be of length M. In the proposed method, all filters are permitted to be of the same length as each other and longer than M. The significance of our proposed method is verified by showing some design examples.
