一种新的变步长自适应噪声消除算法
A Novel Variable Step-Size Adaptive Interference Cancellation Algorithm
摘要
Abstract
Considering the features of carrier power line noise,a novel variable step-size adaptive interference cancellation algorithm is proposed in this paper.A new function relation formula between the varying step-size of adaptive algorithm and gradient is established.this algorithm not only make up for the deficiency of the variable step size algorithm based on the error in the adaptive interference cancellation,but also overcome the limitation of the standard LMS algorithm that its convergence is sensitive to the power of input signal.And the algorithm can adjust step size along with the gradient in order to converge faster.Also,theoretical analysis about the novel variable step-size adaptive interference cancellation algorithm is conducted in this paper,and the performance of the algorithm is verified by simulation and practical results.Simulation and practical results indicate the correctness of theoretical analysis and demonstrates the advantages of this algorithm.关键词
