摘要
介绍了一种基于均方误差估计的新变步长LMS自适应滤波算法。与传统的LMS算法相比,该算法具有较快的收敛速度和较小的稳态失调。将该算法应用于自适应噪声对消系统的仿真中,给出了计算机仿真结果,仿真结果与理论分析一致,证明了新算法的优越性。
This paper propose a novel alterative step LMS auto- adapted filter algorithm based on mean squarederror estimation. Compare to the traditional LMS algorithm, it attains a faster convergence speed and less stability maladjustment . Applying this algorithm to simulate the auto - adapted noise elimination system, simulated results were given out. The results were consistent with the theoretic analysis, which shows the advantage of the novel algorithm.
