摘要
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。
Synchronization is a pivotal techniques in hybrid spread spectrum system,and has a direct bearing on the nomal opertaion of the whole system.This paper proposes a rapid synchronization techniques suitable for the DS/FH hybrid spread spectrum system.Based on the advantages of DS and FH synchronization,this technique tries to realize synchronization of the the whole system in short time and with a simple method.The synchronization of spread spectrum system is divided into two parts,that is,FH synchronization and DS synchronization,thus making the hybrid spread spectrum in exact synchronization.This technique could rapidly realize synchronization,and is of much better synchronization result.
