摘　　要：在多通道有源噪声控制系统的硬件实现中,当通道数目增大或滤波器长度较长时,常规的多通道算法运算量急剧增加,使控制器可能无法实时实现。研究了局部迭代算法在多通道有源控制系统中的应用,讨论了系统选取不同通道数和滤波器长度时,对算法硬件实现的影响。In the hardware implementation of a multi-channel active noise control system, the computational complexity is increased sharply when the number of filter coefficients and channels are increased. In this paper, the partial-update algorithm used in the multi-channel active noise control system is investigated, and a variety of factors influencing the hardware implementation are discussed.
