Resumen
According to the established theoretical model, this study deduces the convergence conditions of the system and obtains the step-size bound suitable for all stages of system operation. The simulation and experimental results show that the system has excellent stability and robustness under extreme conditions; it has a pronounced noise reduction effect for different noise signals and establishes a quiet space. These results have practical guiding significance for other follow-up work, such as variable step size and auxiliary noise power scheduling strategy, as well as the creation of quiet space.
