说明：  介绍了一种用于ip电话的自适应回声消除器，采用LMS自适应滤波器实现。首先通过MATLAB进行LMS算法的步长选择,并用生成的符合G.168要求的带限CCS测试信号对回声消除器的性能进行了测试(Introduced a kind of adaptive echo cancellation ip phone device, using LMS adaptive filter. Carried out by MATLAB first step LMS algorithm selection, and use the resulting band-limited meet G.168 requirements of CCS test signal on the performance of echo cancellation devices were tested)
