| 摘 要： | 非线性系统、弱的驱动信号和适量的噪声:在一定条件下,三者的相互协作使得噪声在一定程度上能够对信号起到增强的作用,这种反常的现象被定义为随机共振.本文以信号的估计与检测为主线,分析了推动随机共振应用发展的信息学与生物学背景,综述了随机共振在工程信号处理方面的最新进展,深入的介绍了一些模型以及存在的问题,并指出了进一步研究的方向.

| Abstract: | Noise sometimes can improve the performance of a signal-processing system when nonlinearity,weak signal and noise coexist.The counter-intuitive phenomenon is termed as stochastic resonance.Based on signal detection and estimation,the information-theoretic and biological background of stochastic resonance is introduced in the paper,and its development history,current and future challenges are reviewed in detail. |

| Keywords: | stochastic resonance signal detection signal estimation nonlinear signal processing implicit stochastic resonance |
