| Abstract: | Based on the principle of the chaos weak signal detection,a new method is presented for Duffing oscillator used to demodulate PSK signal in this paper.Its principle and realization procedure are introduced.The feasibility and the validity of the method were testified by the simulation,and the performance of the method is compared with the traditional methods of PSK signal demodulation. |
