Stochastic Resonance in an Array of Dynamical Saturating Nonlinearity with Second-Order

Abstract

The transmission of weak noisy signal by parallel array of dynamical saturating nonlinearities with secondorder is studied. Firstly, the numerical results demonstrate that the output SNR can be enhanced by parallel array of dynamical saturating nonlinearities with second-order by tuning the internal noise. Secondly, the SR effects can be optimized by the self-coupling coefficient of the dynamical nonlinearity. Then, the SR effects when the nonGaussian noise acts as the external noise are superior to that with external Gaussian noise.
