Research on the Parameters of Bistable Stochastic Resonance System

Stochastic resonance system provides an important means for low signal-to-noise ratio (SNR) signal detection. Based on SNRstudy of the bistable stochastic resonance system, the relationship between the extreme value of output SNR of the system and input noise intensity are analyzed. The results show that when the noise intensity is high level, the system parameter corresponding to the maximum value of the SNR is larger and divergent. At the same time, the time-domain characteristics of the output signal corresponding to the optimal system parameters after multiple optimizations are closer to the actual signal.
