摘要
将跳频同步和跳频组网技术结合起来达到系统同步是跳频通信的关键问题。为了提高同步过程的建立速度和稳定性,分析并比较了同步过程的实现方法,选择了适合的同步方法,并进一步设计了帧结构、组网时隙分配方法等关键技术。根据本跳频电台特有的时分多址接入(TDMA)组网协议,在FPGA上设计和实现了一套跳频电台的TDMA组网同步方案。在Quartus2上对其进行了仿真和分析,结果表明了该方案实现简单、同步快速可靠。
Combining the techniques of frequency hopping（FH） synchronization and FH building-net is the key point of FH system.To improve the speed of the building-net process and the stability of the system,the synchronization method of FH system is analyzed.Also the frame structure and the slot allocation method are designed.According to time division multiple access（TDMA） protocol which is used in our FH system,a scheme for the building-net and synchronization process in FPGA is designed and implemented.The results of simulation in Quartus2 for FH synchronization are also given.This scheme is easy to implement and the process of FH synchronization is fast and reliable.
