Design of perfect reconstruction integer-modulated filter banks
Alfred Mertins, Tanja Karp, Jörg Kliewer · 2003
New methods for the design of integer-modulated filter banks are presented. The novelty lies in the design of the modulation vectors, which are not restricted to certain structures like dyadic symmetry. In addition, an efficient implementation based on Householder factorization is presented. In all cases considered, both the filter prototype and the modulation sequences are composed of integers while maintaining perfect reconstruction for arbitrary input signals.
