摘　　要：基于混沌微弱信号检测的原理,提出一种利用Duffing振子实现PSK信号解调的新方法。介绍了该方法的原理和具体实现过程。仿真结果证明了文中所提方法的可行性和有效性,并将该方法和传统的PSK信号解调方法进行了比较。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.
