| 摘 要： | 因简便易行而在自适应有源噪声控制(AdaptiveActiveNoiseControl,简称AANC)中广泛应用的滤波-XLMS算法(简称FLMS算法),由于其对输入向量自相关矩阵特征值分散程度的敏感性强,从而限制了它在AANC中的应用范围。木文提出了滤波-XMLMS算法(简称FMLMS算法),是在原FLMS算法基础上增加了一个动量项。通过大量的理论分析、计算机仿真和实时实验,证明了该算法在单通道自由声场的AANC中有着比FLMS算法优越的性能。

| Abstract: | Although FLMS algorithm is widely used in Adaptive Active Noise Control (AANC) system due to its simplicity, its applications in AANC is limited because it is intensively sensitive to the disperse of the eigenvalue of the self-correlation matrix of input-signal vector. The FMLMS algorithm proposed in this paper includes a momentum term to FLMS algorithm. From the theoretical analysis, the computer simulations and the experimental results in a half-anechoic room, it is shown that the FMLMS algorithm has more advantages than FLMS algorithm in single-path AANC system. |
