Abstract
An algorithm is proposed for the design of 2L-channel FIR paraunitary filter banks with complex coefficients to meet the requirement of processing complex signals. The filter designed with the algorithm has the property of near linear-phase. Thus, there is no more phase distortions introduced to the phase spectrum.
