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.针对OQPSK调制的特点,提出一种能够同时进行位定时和载波初始相位捕获的并行算法,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,同步速度更快,实现结构简单,适于数字化实现.In high-rate digital mobile burst communication, it is important to acquire the symbol timing and carrier phase offset rapidly. This paper presents an algorithm of symbol timing and carrier phase offset acquisition for OQPSK. Proposed algorithm is parallel and has advantages over serial system that recover the carrier phase offset, and then estimate the symbol timing. This algorithm is easy to realize by using digital technology.
