摘要
由于FXLMS算法结构简单、性能稳定和具有全局收敛的特点,在各种自适应有源噪声控制领域中,多采用FXLMS算法及其改进形式。着重讨论了3种多通道有源噪声控制算法,对3种算法收敛性进行了比较,并利用实际采集的车内噪声对算法性能进行了验证。仿真结果表明3种多通道算法能有效地降低车内的低频段噪声。
FXLMS algorithm and its modified algorithm are widely used in adaptive active noise control system beeanse of its simple structure, stable performanee and eonvergenee. Analysis of three multiehannel active noise control algorithms are given, and the eomparison among these algorithms with computer simulation are diseussed. Result of simulation verified that these algorithms have good performance on attenuating the cabin noise.
