| 摘 要： | 在跳频通信中,收发双方需要根据约定实时地产生跳频序列,以完成跳频同步。不同于通常设计中采用的加入同步码或使用精确时钟等方式,利用可实时获取且精度较高的GPS时间统一信息作为收发双方的参考TOD,依赖FPGA的高速运算能力,可以产生性能较好的调频序列。根据某跳频通信系统的设计需求,设计基于TOD信息的长周期跳频序列产生方法,给出GPS时统信息的提取方法和用于构造跳频序列的m序列寄存器状态计算方法,以及宽间隔化处理实现方法,同时分析了系统的计算时间与生成的跳频序列的性能。

| Abstract: | In the FH(frequency hopping) communication,both the transmitter and receiver need to generate FH sequences according to the appointment to realize FH synchronization.Different from other modes such as the addition of synchronization code or expensive accurate clock,taking GPS time which is accurate and could be got momentarily as the reference TOD of both the transmitter and receiver,the good FH Sequences can be generated based on high-speed calculation capability of FPGA.According to the request of a FH co... |
