Signal Detection Based On Stochastic Resonance

In this paper, stochastic resonance theory is used in signal detection. Here, we mainly talk about the bistable form, in which Langevin equation has been adopted. This paper gives the basic theory and its mathematical reduction of stochastic resonance. Then, some simulations are listed to manifest the performance of this method in signal detection when some parameters change. According to the experiment, the method of stochastic resonance is effective in signal detection.
