摘要
A novel nonlinear detector is proposed using a bistable stochastic resonance system which is constructed by langevin equation.The performance of the detector is analyzed, and the probability of detection(PD), the probability of false alarm(PFA) are deduced by the probability density function (p.d.f) of Fokker-Planck equation. We compared the performance of the proposed detector with that of matched filter detector(MFD),and showed the superiority of the proposed detector over MFD under low signal to noise ratio(SNR)(below -10dB).
