| Abstract: |
| Objective To realize the improved variable step size LMS algorithm on the Simulink platform. Methods Base on basic researches of LMS algorithm, the two aspects of convergence speed and imbalance in the signal processing by variable step size LMS algorithm were explored in details to improve the variable step algorithm and verify the effectiveness of the algorithm. Based on S-function, the model of the improved LMS algorithm was established and the algorithm program was improved by module calls to achieve the purpose of signal filtering. Results The simulation results showed that the algorithm module can achieve algorithm filtering function and effectively counteract interference. Conclusion In the algorithm adopted in Simulink modeling, the algorithm module can be adapted to different Simulink platforms, which improved the efficiency of the development and application of algorithms. |
