摘要： In this paper, we discuss the effects of the error feedback on the output of a nonlinear bistable system with stochastic resonance. The bit error rate is employed to quantify the performance of the system. The theoretical analysis and the numerical simulation are presented. By investigating the performances of the nonlinear systems with different strengths of the error feedback, we argue that the presented system may provide a guidance for practical nonlinear signal processing.
