| 摘 要： | 用线性系统理论的方法对基于Lorenz系统的驱动—响应同步和主动—被动同步保密通信系统的同步鲁棒性进行了理论分析,对所得的同步误差模型做了计算机仿真研究,由此得到这两种同步方法的同步效果,后者的同步鲁棒性优于前者,同步效果理想,保密通信的信号恢复精度高,能够满足实用要求.

STUDY OF ROBUSTNESS OF SYNCHRONIZATION IN THE CHAOTIC SYNCHRONIZED SECURE COMMUNICATION |
| |
| Abstract: | The robustness of synchronization by the drive response method and the active passive decomposition method in the Lorenz system was analyzed using control theory. The approximate analytical synchronization error models were established to describe the synchronization behaviors. The simulation results indicate that the active passive decomposition synchronization is both more robust and better in signal recovery precision than drive response method, so it is more applicable. |
