A generalized algorithm for linear-phase paraunitary filter banks
Li Chen, Kwok-Ping Chan, Truong Q. Nguyen · IEEE Transactions on Signal Processing · 1998
A new algorithm for a subclass of linear-phase paraunitary filter banks with generalized filter length and symmetry polarity is reported. New properties in the polyphase matrix are derived, and the lattice factorizations for filter banks with an even and odd number of channels are examined in a generalized algorithm.
