摘要
同步技术是跳频系统的核心。本文针对FPGA的跳频系统,设计了一种基于独立信道法,同步字头法和精准时钟相结合的快速同步方法,同时设计了基于双图案的改进型独立信道法,同步算法协议,协议帧格式等。该设计使用VHDL硬件语言实现,采用Altera公司的EP3C16E144C8作为核心芯片,并在此硬件平台上进行了功能验证。实际测试表明,该快速同步算法建立时间短、同步稳定可靠。
Synchronization is the core technology of Frequency Hopping Spread Spectrum （FHSS） System. This paper designs a fast synchronization method for FHSS system based on FPGA, which combines the method of independent channel, synchronization-head and precision clock. This paper also designs an improved independent channel based on two hopping patterns, protocol of synchronization algorithm and frame format of the protocol. Practical application shows that this synchronization method is fast and reliable.
