Study on Stochastic Resonance Theory for Weak Signal Detection

Wang Shu-min

Abstract

The basic principle of stochastic resonance is introduced,and the existing method of detecting weak signal using stochastic resonance theory is analyzed,then a improved detection algorithm of stochastic resonance is put forward.This method is much more precision for weak signal extracted.The simulation results show that the method is feasible.
