同步技术是混合扩频系统中的关键技术之一,它直接关系到整个系统能否正常工作。介绍了一种适用于DS/FH混合扩频的快速同步技术,根据解扩的顺序,利用直扩系统和跳频系统同步技术的优点,以求在较短时间内用较简单的方法实现整个系统的同步。根据这个思想,将扩频系统的同步划分成两个部分:跳频码同步和直扩码同步,从而最终使整个混合扩频系统精准同步。本方法能够快速同步,大大缩短同步时间,同步效果好。
Synchronous technology is a hybrid spread spectrum system, one of the key technologies, which is directly related to the entire system can work properly. This paper introduces a kind of fast synchronization technology which is suitable for DS / FH hybrid spread spectrum. According to the sequence of despreading, the advantages of DSS and frequency hopping system synchronization are introduced in order to realize the whole System synchronization. According to this idea, the synchronization of spread spectrum system is divided into two parts: frequency hopping synchronization and DSSS synchronization, which ultimately make the hybrid hybrid spread spectrum system accurately synchronized. The method can quickly synchronize, greatly shorten the synchronization time, the synchronization effect is good.
