In this paper, we propose a new subband adaptive filter (SAF) structure and derive a new adaptive filter coefficients algorithm according to the principle of minimal disturbance. The proposed new structure is based on the two-stage subband decomposition, which can generalize old SAF structures, and therefore lead a novel insight into SAF structure. We also present the Complexity analysis. Compared to the old structure with one-stage decomposition, the new structure exhibits faster convergence rate in similar complexity. Simulation results validate the efficacy of the new proposed structure.
