Abstract

Many problems in communication and Radar signal processing involve the detection of low signal to noise ratio (SNR) signal in non-Gaussian noise environment. The stochastic resonance of the nonlinear bistable systems driven by binary phase shift keying signal under the alpha stable distributed noise was investigated. Firstly, the detection model of nonlinear bistable stochastic resonance system was constructed, driven by binary phase shift keying (BPSK) signal and alpha stable noise. Then, the effect of the Alpha stable noise intensity and system parameters on the output signal-to-noise ratio(SNR) and SNR gain were explored. The results show that separate adjustment of system parameters a and b or noise parameters m can produce stochastic resonance phenomenon and achieve enhancement of the input signal. Moreover, existence the optimal values of a ,b and m can be make the output of the system resonance is the strongest, which can effectively detect the weak input signal.
