Method of Realizing Chaotic Masking Communication Based on Duffing System

Duffing方程是一种重要的动力系统。研究了该系统的数学模型,通过变量分解的方法改变了系统的结构,并证明了运用新结构的Duffing系统实现混沌掩盖的合理性,最后给出了新Duffing系统的运行轨迹和混沌掩盖通信的解调结果。仿真结果表明,所提出的方法是正确有效的。

Dulling equation is a kind of important power system. The mathematic model of this system was studied in this paper. Structure of this system was changed with the variable decomposition method, and it was also proved that applying Dulling system with new structure to realize chaotic masking is rational. At the end of this paper, the running tracks of new Dulling system and the demodulation results of chaotic masking were given. Simulation results show that the method proposed here is correct and effective.
