Simulation of Adaptive Filter Based on LMS Algorithm in Simulink

摘要

The paper introduces the principle and structure of adaptive filter based on LMS algorithm, studies a design scheme of a single frequency adaptive notch filter, and simulates its working procedure by using the Simulink simulation tool. The simulation results show that the adaptive notch filter based on LMS algorithm has the better convergence and the smaller steady-state error than traditional notch filter in the appropriate parameter.
