【摘要】 作者采用了MLMS算法自适应消噪声器来消除肺音信号中的心音干扰。MLMS算法对步长因子μ的选择限制不严;可以选得比LMS算法所用的大得多,以增加自适应跟踪速度。本文介绍了应用的实际效果。更多还原

【Abstract】 The author used MLMS algorithm-adaptive cancellation to remove heart sound from breath signal, The step size μ in MLMS algorithm is not critical, and μ may be much larger than in LMS algorithm to increase adaptive tracking rate. The paper introduces the result of the cancelling.更多还原
