Integer-Modulated Filter Banks Providing Perfect Reconstruction, Alfred Mertins, Tanja Karp, Jorg Kliewer
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we extend the perfect reconstruction conditions known for cosine modulation to other, more general modulation schemes. The modified PR conditions provide additional degrees of freedom which can be utilized to design integer-modulated filter banks. Techniques for the design of prototypes and modulation sequences are presented.
