Abstract

Generalized algorithms are proposed for linear-phase paraunitary filter banks with pairwise-mirror-image frequency responses.The proposed algorithms promote fast convergence of design process.When the number of channels is even

a generalized linear factor is proposed that has additional free parameters and helps to improve the characteristics of the filters.When the number of channels is odd

a new structure is proposed.
