Abstract:

A nonlinear single neuron is demonstrated to exhibit stochastic resonance by theoretical analysis and numerical simulations. This single neuron is used for noisy periodic signal transmission, and significant performance of raising input-output SNR gain can be achieved. The research of this paper not only gives a very simple model of neuron with stochastic resonance, but also enlarges the application scope of neuron to the transmission of periodic signals.

利用理论分析和数值仿真的方法证明了一种简单的非线性神经元存在随机共振现象, 并将该神经元用于含噪声方波脉冲信号的传输, 结果表明该方法可以有效提高信号传输系统的输入输出比增益, 从而大大地抑制了信号中的噪声.本文的研究不仅给出了一种具有随机共振现象的简单神经元模型, 而且将神经元的应用推广到周期性脉冲信号的传输领域.
