Abstract :
This paper studies the active noise control technology. The S-LMS algorithm is proposed to solve the issue of the main-square-error with the variety of the useful power of the signal linearly. The parameter changes the step size of the weight vectors for the adaptive filter according to the output power of the given system. Then the S-CLMS algorithm is considered to improve adaptive filter performance by using switched adaptive filters. The simulation illustrates that a better performance and a more improvement result of the signal performance are achieved by using the S-LMS algorithm than using the LMS algorithm or the S-CLMS algorithm.
