摘要
给出了一种改进的 L MS算法 ,该算法解决了算法收敛时间和稳态误差间的矛盾 ,为实际应用提供了更大的灵活性。它应用误差信号的相关值去调节步长 ,同时实现了均方误差小和收敛速度快 ,并且降低了 L
This paper introduces a modified LMS algorithm, and propose algorithm allows more flexibility of misadjustment and convergence time without the compromise one for the other. It uses the correlation of output error signal to adjust the step size and to obtain low mean square error and fast convergence.At the same time, it decrease the sensitivity of noise on LMS algorithm.
