Abstract(in English) | The MEFX LMS algorithm is ordinarily used as an update algorithm of the adaptive filter coefficients in the multiple-channel ANC system. However, when we use the algorithm, there is a problem that the condition for stable control is unknown when the modeling errors exist in C^^^ filters. In this paper, we derive theoretical formulae for stable condition and show its effectiveness by expanding the derivation method of the stable condition in the Filtered-x LMS algorithm for the single-channel ANC system into that in the MEFX LMS algorithm for the multiple-channel ANC system. And, we show the theoretical formulae can also apply to the modeling errors of any distributions. Moreover, we study the convergence properties in frequency domain. |
