摘　　要：随着科技的高速发展,人们对信号处理的实时性、准确性和灵活性的要求越来越高,自适应滤波器在信号处理中的地位也越来越重要。自适应滤波器是一种含复杂算法的处理器,它的实现主要采用最小均方误差算法,通过调整滤波器系数来实现滤波,以便更好地跟踪信号的变化,最终实现自适应滤波。本文在Matlab环境下设计出自适应滤波器,验证了它的性能。With the rapid development of technology,people have a higher requirment of real-time processing,accuracy and flexibility of signal,and adaptive filters play an important role in signal processing.Adaptive filter is a processor which has complex algorithms.Adaptive filters are implemented mainly by the LMS algorithms,it can track the signal better by regulating filter＇s coefficient,and finally implement the adaptive filtering.This article designs adaptive filter in the Matlab environment,and verifies its performance.
