Title: Frequency Modulation Stochastic Resonance to Achieve the Parameters of Signal Detection
Abstract: To break the restraint of the traditional stochastic resonance only to detect low frequency signal,the method which uses the detected signal and background noise modulating frequency is proposed to realize that the weak signal can be distinguished from the strong noise in the case of big parameter.The spectrum of the signal by frequency modulation is analyzed.Theoretical analysis and numerical simulation declare that the method can lower the intensity of the noise,and the low frequency quantity of the signal in frequency modulation can generate conspicuous stochastic resonance.
