Abstract

Although complex Lü systems have been considered in many studies, application of the self-time-delay synchronization (STDS) of complex Lü systems in secure speech communications does not appear to have been covered in much of the literature. Therefore, it is meaningful to study the STDS of complex Lü systems and its application in secure speech communication. First, a complex Lü system with double time-delay is introduced and its chaotic characteristics are analyzed. Second, a synchronization controller is designed to achieve STDS. Third, the improved STDS controller is used to design a speech communication scheme based on a complex Lü system. Finally, the effectiveness of the controller and communication scheme are verified by simulation.

摘要

尽管在许多研究中都考虑过复杂的吕系统，但复杂吕系统的自时延同步（STDS）在安全语音通信中的应用在很多文献中似乎并未涉及。因此，研究复杂吕系统的STDS及其在安全语音通信中的应用具有重要意义。首先，引入了具有双时延的复杂吕系统并分析了其混沌特性。其次，设计了一个同步控制器以实现STDS。第三，使用改进的STDS控制器设计了一种基于复杂吕系统的语音通信方案。最后，通过仿真验证了控制器和通信方案的有效性。
