Abstract :
Based on the principle of the chaos theory of weak signal detection, a new method is presented for Duffing oscillator used to demodulate 2FSK signal in this paper. The method can demodulate the 2FSK signal under strong noise background in the signal-to-noise rate at -25dB. Finally, the feasibility and the validity of the method were testified by the simulation.
