Abstract

A frequency-domain adaptive filter (FDAF) with a parallel structure and reduced computational complexity for precise adaptive system identification has been proposed. However, the presence of additive noise degrades the performance of the FDAF, and the degradation is conspicuous in the worse case input signal. We propose a new FDAF which improves the performance of the conventional FDAF for system identification in the presence of additive noise and colored input signal.

具有彩色输入信号的鲁棒频域自适应滤波器

提出了一种具有并行结构和降低计算复杂度的频域自适应滤波器(FDAF)，用于精确的自适应系统辨识。然而，加性噪声的存在会降低FDAF的性能，并且在最坏的情况下，这种下降是明显的。我们提出了一种新的FDAF，改进了传统FDAF在加性噪声和有色输入信号存在下的系统识别性能。
