混沌脉冲位置调制的无混沌同步保密通信系统的研制
|
摘要
本文以非线性动力学系统理论为基础，论述了无线混沌保密通信的相关理论及发展历史和现状，并着重讲述了混沌脉冲位置调制(chaotic pulse position modulation)这一新颖的通信技术，和利用此技术实现的无混沌同步的无线保密通信系统。本系统基于Logistic映射，构造混沌序列发生器，用硬件算法实现混沌脉冲位置的调制和解调。发送端将二进制信息序列调制于脉冲序列的间隔中，然后送入无线信道。接收端根据发送端的相关规则，进行非混沌同步的逆运算，恢复出二进制信息序列。
该系统直接用硬件实现混沌迭代算法，运用混沌脉冲位置调制技术实现无混沌同步通信。系统在实验室环境调试通过。
本系统的成功研制证明了无混沌同步通信的可行性。系统具有很高的保密性，具有防误码扩散，抗干扰能力强等特点，同时也为混沌保密通信应用于脉冲无线电系统以及混沌脉冲位置调制的多址通信方面做了一些实质性和探索性的工作。
Based on the theory of nonlinear dynamics system, this paper discusses the theory about wireless chaos security communications and its history and status quo of development, then emphasizes the new communication technology-chaotic pulse position modulation, and the realization of non-chaos synchronization wireless security communication system using the technology. This system based on Logisitic map. It designs a chaos sequence generator and realizes the modulation and demodulation of chaotic pulse position by hardware. In the send site, binary message sequence is modulated between pulse sequences, then took it into wireless channel. In the receive site, we operate non-chaos synchronization in reverse and resume binary message sequence by the correlated rule of the sender.
This system realize the chaos arithmetic directly by hardware and non-chaos synchronization communication by chaotic pulse position modulation technology. The system is running ok in the laboratory.
The success of this system proves the non-chaos synchronization communication feasibility. The system has a good security and can prevent the pervasion of mistake code, has a well anti-jamming ability and so on. Some substantial and groping work has been done in the process of using chaos security communication in pulse wireless system and the multi-access communication of chaotic pulse position modulation.
