Stochastic resonance quantified by statistical complexity measures in a bistable system subject to colored noise

This work deals mainly with the problem of the stochastic resonance in a symmetric bistable system subject to colored noise by virtue of the statistical complexity measures. Firstly, based on Bandt–Pompe methodology, the statistical complexity measures are dedicated to quantify the stochastic resonance of the system. Then, the effects of the correlation time of the colored noise, the amplitude and the frequency of the signal on the stochastic resonance are discussed by using the statistical complexity measures. Meanwhile, the SNR is also given for the purpose of verifying the validity of this approach. It is turned out that the statistical complexity measures can be used to characterize some subtle signatures of noise-induced phenomena. Additionally, the robustness of the results is verified with reducing the embedding dimension and the total length of the time series.
