摘要
非线性系统中,噪声改善系统性能的现象称作随机共振。文中简单回顾了随机共振研究中取得的主要成果,着重分析了随机共振在统计信号处理领域的研究进展,展示了在不同的信号处理要求或准则下噪声改善检测或估计性能的功效。最后提出研究中的问题,并对随机共振的发展作了展望。
Stochastic resonance (SR) is a phenomenon for improving performance of some nonlinear systems by noises. This paper reviews main results on stochastic resonance and then focuses on the research advances in the field of statistical signal processing where the theory of SR is applied. Meanwhile, we dis- play the efficiency of noise-enhanced-detection or noise-enhanced-estimation is displayed on diverse crite- ria. Finally, some open problems are proposed and prospects for the development of SR are given.
