Detection of Cycle Signal and Non Periodic Signal Based on the Principle of Stochastic Resonance

阐述随机共振的基本概念和原理,分析基于随机共振原理检测微弱信号的方法。采用RungeKutta算法分别对微弱的周期信号和非周期信号进行仿真验证,仿真结果表明基于随机共振原理可以有效地检测出强噪声背景下的微弱信号。

This paper expounded the basic concept and principle of stochastic resonance,and analyzed the detection method of weak signal based on the principle of stochastic resonance.Using Runge Kutta algorithm,the weak periodic signal and aperiodic signal were simulated,and the simulation results show that,based on the principle of stochastic resonance,the weak signal in strong noise background can be effectively detected.
