基于双稳耦合系统的随机共振信号复原
Stochastic resonance signals recovery based on bistable coupling systems
摘要
Abstract
A bistable coupling system for the inversion and bistable systems was established to recovery noisy periodic signal directly.According to the influence of each system parameters to stochastic resonance process,an adaptive adjusting method for the optimal system parameters was applied.Through sampling noisy periodic signal and estimating the noise variance,the signal frequency,the maximum signal to-noise ratio was regarded as optimization objective to determine the optimal parameters of the system.The simulation results show that this method has a fast and accurate signal resto ration effect.关键词
