该文讨论了在非周期信号驱动下,误差反馈对随机共振双稳态非线性系统滤波输出的影响。该文首先导出了势函数和动态概率密度函数,并采用由动态概率密度函数定义的误比特率来衡量随机共振双稳态非线性系统在二进制随机信号下的滤波性能。最后通过理论分析与仿真实验验证所得结果的正确性。该文旨在研究误差反馈对随机共振系统输出的影响,针对不同的反馈强度,对相应系统的性能进行比较,为非线性系统中的信号处理提供一种新思路。
In this paper, we discuss the effect of error feedback on the output of a stochastic resonance bistable nonlinear system driven by aperiodic signals. In this paper, the potential function and dynamic probability density function are derived firstly, and the bit error rate defined by dynamic probability density function is used to measure the filtering performance of stochastic resonance bistable nonlinear system under binary random signal. Finally, the theoretical analysis and simulation experiments verify the correctness of the results obtained. The purpose of this paper is to study the effect of error feedback on the output of a stochastic resonance system. According to different feedback intensities, the performance of the corresponding system is compared to provide a new idea for signal processing in nonlinear systems.
