局部序列匹配自同步法是一种新的跳频自同步方案。在跳频工作状态,接收机使用很少的支路接收具有某种特征 的发送序列,将此序列与本地序列匹配,确定接收端与发射端的跳频序列相位差,调整相位完成同步捕获。文中给出了局 部序列自同步法的原理描述和设计方案,并在高斯白噪声环境下进行了性能分析。分析结果表明,该方案不需要同步引 导码和勤务频率,具有较强的抗侦察能力和抗干扰能力。

[Abstract]
Partial sequence matching self-synchronization scheme is a new FH self-synchronization scheme. In FH working status, the receiver gets some characterized transmitting sequence with few of branches, which will be matched with local hopping sequence. The phase difference between the receiver and the transmitter can be calculated, which is adjusted to make system synchronization. The principle description of partial sequence matching self-synchronization scheme is given and this scheme designed. The scheme performance is analyzed in Gaussian white noise environment. The results show that, this scheme makes system hold synchronization and late entry synchronization without any synchronization lead code and service frequency, and it has a strong anti-reconnaissance and anti-jamming capability.
