摘要
主要讨论了应用于多通道有源噪声控制系统的自适应组合逆算法及其性能分析。通过对该算法的理论推导,阐明其整体思路及物理意义,同时通过在同参数条件下与FxLMS算法的计算机仿真比较,得出结论:在多通道有源控制中,组合逆算法有效地降低了算法运算量,适合应用于多通道系统。
A combined adaptive inverse algorithm is applied to a multichannel active noise control system, and its computational load and performances are analyzed in this paper. First, the algorithm and its physical meanings are examined,then it is derived that the computational load of Combined Filtered-e LMS algorithm can be largely reduced in the field of mutichannel active control in comparison with the commonly used Filtered-x LMS algorithm.
