一种改进的LMS算法及其在噪声对消中的应用
AN IMPROVED LMS ALGORITHM AND ITS APPLICATION IN NOISE CANCELLATION
摘要
Abstract
Based on the analysis of traditional LMS algorithms with fixed step size and variable step size, this paper presents an improved variable step size LMS algorithm. By utilizing the exponential form of the cube of instantaneous error's absolute value and the forgetting factor simultaneously, the new algorithm adjusts the step size so that it better solves the contradictions of convergence speed and steady error. Applying three algorithms to noise cancellation and comparing them, the simulation results show that, the new algorithm performs better than conventional fixed step size LMS algorithm and variable step size LMS algorithm in convergence rate.关键词
