| 摘 要： | 为了降低突发噪声对混沌通信系统的影响,提出一种降低混沌接收系统混沌同步时间的方法.通过对系统模型状态变量导数的系数进行调整,增强了系统的同步能力,缩短了同步所需时间.仿真结果表明,该方法能够有效降低混沌接收机同步所需时间,调整后系统的同步时间为原系统的1/20.该方法能有效抵御突发噪声干扰对通信系统的影响,提高混沌调制通信系统的通信质量.

| Abstract: | To reduce the effect of the gusty noise to the chaotic communication system, a method was developed to enhance the synchronization ability and reduce time expenditure by adjusting the differentiation with respect to the state variables in the chaotic system. Simulation results show that the method can reduce the time expenditure of the chaotic synchronization and the time expenditure of synchronization of the new system is about 1/20 of the original system. The method has the ability to resist the gusty noise in the channel and improve the quality of the chaotic communication. |
