Complex-valued linear-phase paraunitary filter banks

An algorithm is developed for the design of complex-valued linear-phase paraunitary filter banks. The designed filter banks have, for the first time in the design of sub-band filter banks, complex-valued filter responses. The difference between a real-valued and complex-valued linear-phase paraunitary filter bank is that conjugate-centro-symmetric matrices are employed. Filter banks with 8 and 16 channels were presented to validate the algorithm.link_to_subscribed_fulltex
