基于LMS算法和NLMS算法的自适应声回波消除器AEC，实现的主要功能是：在用户对电视发出的指令混杂了电视扬声器的声学回声的情况下，滤掉电视声音得到较为纯净的用户语音指令信号。-The main function of the adaptive filter based on the LMS algorithm and the NLMS algorithm is mixed: in the instruction issued by the user on the television TV s

自适应滤波器是用在线方式完成近似步骤的一种滤波器，通过调整参数让输出使包含参考信号的某个特定目标函数最小化-The adaptive filter is used to complete an online approximation step of the filter , so that by adjusting the parameters so that the output of a particular objective function containing the refere
