| 摘 要： | 针对自适应有源消声最常用的滤波—XLMS算法(FLMS)运算量小、收敛缓慢、宽带消声效果差等不足之处,利用误差通道滤波特性,提出了变换域滤波—XLMS算法。新算法的突出优点是收敛速度较快、宽带消声效果较好。

| Abstract: | The most commonly used algorithm for adaptive active noise control (AANC) is filtered -X LMS (FLMS) algorithm which is not suitable for active control of wideband noise because of its slow convergence rate. In this paper, a transform domain filtered-X LMS algorithm which converges much faster than FLMS algorithm is presented. The computer simulation has shown its efficiency in controlling broadband noise. |
