同步技术是跳频通信系统的关键技术之一,尤其是在快速跳频通信系统中,常规跳频通信通过同步字头携带相关码的方法来实现同步,但对于快跳频来说,由于是一跳或者多跳传输一个调制符号,难以携带相关码。对此引入双跳频图案方法,提出了一种适用于快速跳频通信系统的同步方案。采用短码携带同步信息,克服了快速跳频难以携带相关码的困难。分析了同步性能,仿真结果表明该方案同步时间短、虚警概率低、捕获概率高,同步性能可靠。 Abstract: Synchronization is one of the key techniques to frequency-hopping communication system, especially in the fast frequency hopping communication system. In conventional frequency hopping communication systems, synchronization can be achieved by synchronization-head which can be used to carry the synchronization information, but for the fast frequency hopping, Because modulation symbol is transmitted by per hop or multi-hop, it is difficult to carry the correlation code. For the limitation of fast frequency hopping in carrying correlation code, a fast frequency-hopping synchronization scheme with two hopping patterns is proposed. The synchronization information is carried by short code, which overcomes the difficulty of correlation code transmission in fast frequency-hopping. The performance of the scheme is analyzed, and simulation results show that the scheme has the advantages of shorter synchronization time, lower probability of false alarm, higher probability of capture and more reliable of synchronization.
