摘要 快速取得载波同步和位时钟同步是突发模式通信系统的基本要求。该文提出了突发模式OQPSK接收机的一种快速同步算法。该算法使用一个特定图案的前导字,在前导字期间经过适当处理,将待估计的载波相位和垃时钟相位分开,然后采用开环方法进行并行、独立地估计。理论分析和模拟结果表明,该算法可快速建立载波同步和位时钟同步,并可应用于卫星通信、移动通信等场合。 Rapid carrier and bit-tirning synchronizat,ion are esseutial in burst mode commu-mication .systems. A new algorithm for fast synchronization in a burst mode OQPSK receiver is proposed in this paper. The algorithm is based on a specific bit-pattern preamble, which allows total decoupling of the carrier phase and bit-tirning phase aud thus permits direct , sinmltaneous estiniating of the reference pararrieters by open-loop approach. It is shown that the algorithm achieves a signih'cantly agile carrier and bit-tirning recovery. The algorithm is applicable to satellite communication systems, rnobile communication systems etc.
