随机共振技术检测弱信号的两种方法的比较研究

Comparision of two ways on the application of stochastic resonance in bistable system for detection weak signal

详细介绍利用随机共振技术检测微弱周期信号的原理,采用增加噪声强度及调节系统参数2种方法提取周期弱信号,相应的给出了数值模拟仿真实验,由此得出2种方法具有协调统一性.

Deals with a novel approach to detecting weak periodic signal using stochastic resonance theory. Numerical simulation of extracting weak periodic signal from noise background by adding noise intensity and tuning systems parameters is presented. And the two ways is consistent.
