摘要

摘要: 混沌无线数字通信是未来高安全高保密无线通信的重要发展方向，而混沌码同步是其核心技术之一。该文根据混沌无线通信特点，提出一种基于滑动相关峰检测的混沌码同步方法。针对非周期混沌码同步，设计了在混沌码同步3个约束条件下的相位延迟控制模块，搭建了基于Logistic序列的同步系统动态模型，并进行了仿真。仿真结果表明，该方法可实现收发两端混沌码同步，同步速度快，抗噪能力强，有效地解决了混沌无线数字通信中的同步方法问题。

Abstract: Chaos wireless digital communication is an important development direction of high security wireless communication in the future. Chaos code synchronization is one core technology. According to characteristics of chaos wireless communication, a method of chaos code synchronization based on sliding correlation is put forward. For non-periodic chaos code synchronization, phase delay controller is designed under the condition of three constrain conditions. Taking logistic sequence for example, a dynamic model of chaos code synchronization system is built and the simulation is carried out. The test results show that this method can effectively realize chaos code synchronization between sender and receiver. Its synchronous rate is fast and anti-noise performance is good. It solves the synchronization problem in chaos wireless digital communication.
