Design of generalized linear-phase paraunitary filter banks with zeros at mirror frequencies


In this paper, we present a novel lattice structure and design of the linear phase M-channel paraunitary filter banks whose filters all have zeros at the mirror frequencies except for the passband. This structure is implemented by replacing the first block of the lattice structure with two type II DCTs. With this structure, the filter banks are implemented… (More)
