摘 要: | We manifest a stochastic resonance in a two-dimensional square array of coupled oscillators subjected only to white noise and constant driving forces.The result shows that the coherent output of every single oscillator plays the role of periodic input to its neighbours.Even without periodic driving,the cooperation of the white noise and the coupling can also result in the array enhanced stochastic resonance effect.In our investigation,global as well as local noise perturbation is taken into account.
