中文说明：
基于lms算法的干扰自适应抵消，LMS算法是基于最陡下降法的统计估计的最小均方值算法，令误差的均方值达到最小时的抽头系数的值即为最优解。LMS算法抽头系数w的变化方向为代价方程的负梯度方向。
English Description：
Adaptive interference cancellation based on LMS algorithm. LMS algorithm is the minimum mean square algorithm of statistical estimation based on the steepest descent method. Making the mean square value of error reach the minimum tap coefficient is the optimal solution. The change direction of the tap coefficient w of LMS algorithm is the negative gradient direction of the cost equation
