【Abstract】 The least mean square(LMS) algorithm and the system structure of an adaptive filter based on the LMS algorithm are introduced briefly. Then the MATLAB program and its result are described. The result of simulation using SIMULINK is also presented. The effect of the iterative step on the performance of the system is analyzed. The presented algorithm is easy to be implemented and the difference between the accurate value and the result obtained by using the LMS algorithm is acceptable in practical application.更多还原
