摘　　要：在高速数字突发通信中，需要快速、高效地对接收信号的位定时和载波初始相位信息进行估计。本文提出一种能够同时进行位定时和载波初始相位同步的并行算法，与传统的先进行载波恢复，再进行位定时捕获的串行处理相比，该算法同步速度更快（8-12个符号），实现结构简单，适于数字化实现。In high-rate digital mobile burst communication, it is important to recover the symbol timing and carrier phase offset rapidly. This paper proposes a novel simultaneous carrier and bit-timing recovery algorithm. Compared the traditional with serial system that recover the carrier phase offset first and then estimate the symbol timing, this system is easy to be realized by using digital technology and can complete synchronization within 8-12 symbols.
