Abstract:
An active noise reduction system is provided for receiving an audio input signal and a noise interference signal and calculating an audio broadcasting signal according to a Feedback Filtered-X Least-Mean-Square (FFXLMS) algorithm, wherein the FFXLMS algorithm optimizes a (convergence factor) μ so as to decrease the numbers of divisions operated by the active noise reduction system and increase the operation speed of the active noise reduction system.
