| 根据连续时间混沌系统可由单变量及其导数重构相空间的原理, 采用混沌观测器同步方法, 研究了统一混沌系统的同步控制问题. 基于连续系统的稳定性准则, 提出了统一混沌系统的混沌观测器同步定理. 将该同步方法应用于保密通信, 设计了基于时分复用的混沌掩盖保密通信新方案, 并对该方案的保密性能进行了分析. 基于MATLAB的数值仿真结果证明了同步控制方法和保密通信方案的有效性. |
| 英文摘要 |
| According to the principle of phase-space reconstruction of a continuous time chaotic system by a single variable and its derivative, the synchronization of a unified chaotic system is investigated by employing the chaos observer synchronization method. A theorem about chaos observer synchronization of unified chaotic system is put forward based on the stability rule for continuous systems. Applying this synchronization method to security communications, we designed a new scheme of chaotic masking security communications based on the technology of time division multiple, and carried out its performance analysis. Simulation results on Matlab 6.5 confirm that both the synchronization approach and the security communications scheme are effective. |
