同步是跳频通信的前提,对同步的主要要求是同步检测概率高和同步建立时间短。从实际的跳频系统出发,本文提出了一种实时搜索最佳同步频率的同步方案。经计算机模拟,表明该方案能达到接近1的同步检测概率,同步建立时间及其它各项指标也均满足要求。文章介绍了方案的工作过程,给出了实现的软件流程图,着重分析了方案的初始同步性能,从理论上验证了该方案的可行性。
Synchronization is the premise of frequency hopping communication. The main requirements for synchronization are high synchronization detection probability and short synchronization establishment time. Starting from the actual frequency hopping system, this paper presents a real-time search for the best synchronization frequency synchronization scheme. The computer simulation shows that the scheme can reach the probability of synchronization detection close to 1, the time of synchronization establishment and other indicators also meet the requirements. This paper introduces the work process of the program, gives the software flow chart of the implementation, emphatically analyzes the initial synchronization performance of the program, and proves the feasibility of the scheme theoretically.
