Group Lifting Structures for Multirate Filter Banks II: Linear Phase Filter Banks
Group Lifting Structures for Multirate Filter Banks II: Linear Phase Filter Banks
The theory of group lifting structures is applied to linear phase lifting factorizations for the two nontrivial classes of two-channel linear phase perfect reconstruction filter banks, the whole- and half-sample symmetric classes. Group lifting structures defined for the reversible and irreversible classes of whole- and half-sample symmetric filter banks are …
