摘要：
For highly noisy system, a novel subband adaptive filter, which is called improved affine projection subband adaptive filter (I-APSAF), is proposed. The proposed algorithm is obtained by reusing the past tap-weight vectors, which can achieve faster convergence compared to the existing algorithm. Simulations in an acoustic echo cancellation (AEC) context show that the I-APSAF achieves a lower steady-state misalignment than the normalized subband adaptive filter (NSAF), IMSAF, and improved normalized subband adaptive filter (INSAF).
