分布式跳频通信系统的动态双频同步方案研究
|
摘要
如何保证己方正常通信,避免来自敌方的干扰,已成为通信对抗中的一大难题。跳频通信具有很强的抗干扰、抗衰落、抗截获能力,兼有能多址组网应用等诸多优点,在现代军事通信尤其是战术抗干扰电台中获得了广泛的应用。
跳频同步技术是跳频通信的关键技术之一,迅速、可靠的建立同步是跳频通信系统的重要环节。本文在分析若干跳频同步方法的基础上,提出了一种分布式动态双频跳频同步方案。这种跳频同步方案,采用由混沌伪随机序列控制的分布式跳频序列、双频率跳变和频率预置捕获同步方式,支持多用户的具有分布式局域网络结构的跳频通信系统,具有同步保持实现简单、信号传输速率快、抗干扰能力和抗截获能力强的特点,还能实现跳频通信系统的信号无缝传输和中继传输,收发信号免切换。同时本文利用Matlab7.1/Simulink仿真平台,建立了一个分布式动态双频同步方案仿真模型,基于Logistic混沌模型,采用普适的均匀化算法实现了跳频序列的均匀分布,以DDS为频率合成器实现了动态双频,结合频分多址与码分多址方案,实现了地址码的分配,并与传统的跳频同步方案进行了对比,仿真结果表明,该同步方案实现简单,在跳频增益为3时,抗宽带阻塞干扰的平均误码率可达到10~(-3),是一种构建战术跳频电台局域网络的理想同步方案。
The issue of how to protect regular work from interference caused by aggressive devices has become a big problem. Frequency-hopping (FH) has great advantages of anti-jamming, low interception, anti-fading as well as the application in multi-address networking. So, FH has been widely used in modern military communication, especially in tactial anti-jamming radios.
The synchronization is one of technologies in FH communication, and it is the key link to establish synchronization quickly and reliably in FH communication. Based on the research of frequency hopping (FH) communication system, a new synchronization method-dynamic double frequency synchronization method is proposed. This method adopts distributed FH sequence controlled by chaotic, hopping with double frequence and frequency presets and acquisition, supports multi-user FH communicaton with distributed construction of WLAN. It has the strong ability of quick transmitting baud rate, anti-jamming, relay transmission and no switching in both transmitting and receiveing signals. A model of FH communicaton system is established through Matlab's Simulink. According to Logistic system, universal algorithm is adopted to produce chaotic sequences. DDS is chosen as the frequency synthesizer, and the assignment of addresses is realized by combing FDMA with CDMA .It is compared with traditional FH synchronization scheme. The results show that the synchronization method is simply accomplishing, and anti-jamming to broadband can reach 10~(-3) when frequency hopping gian is 3. This sheme is an ideal scheme for construction of tactical FH radio.
