摘要

分析了用于主动噪声控制(ANC)的滤波- x LMS (FXLMS)算法的行为。自适应滤波器的脉冲响应与主路径之间的相关性被视为宏观变量。为了得到相关性，我们对方程进行解析求解，最后计算出均方差。特别地，我们分析了多通道ANC的行为。我们从理论上表明，MSE受到非直接连接的辅助路径的影响。

Statistical-mechanical analysis of the FXLMS algorithm for multiple-channel active noise control

We analyze the behaviors of the Filtered-X LMS (FXLMS) algorithm for active noise control (ANC). Correlations between the impulse response of an adaptive filter and a primary path are treated as macroscopic variables. To obtain the correlations, we analytically solve the equations and finally compute the MSE. In particular, we analyze the behaviors of multiple-channel ANC. We theoretically show that the MSE is affected by the secondary paths that are not directly connected.
