摘要：
This article put forward a new method on 2FSK signal demodulation by using Duffing Oscillator based on the theory of weak signal detection in Chaotic System. In this paper we utilize the regulation of the wave form generated by the chaotic system when it is detecting the weak signal and combined with the modulation method of 2FSK signals to analyse the demodulation of 2FSK signal in the background of strong noise and construct a Matlab/Simulink simulation model, the result proved the feasibility and effectiveness of this method.
