摘要

本文研究了高数据速率MPSK系统的联合帧同步和相位模糊解决问题。本文提出了一种利用简化的相关运算降低计算复杂度的新方法，该方法使用两个阈值同时检测帧起始点和相位模糊值。针对高数据速率系统，设计了帧同步器并行结构，可同时进行相位模糊度解析。仿真结果表明，该系统能达到预期的效果。

The research on joint frame synchronization and phase ambiguity resolution for high data rate M-PSK systems

This paper deals with the problem of joint frame synchronization and phase ambiguity resolution for high data rate MPSK systems. We presents a novel method of utilizing a simplified correlation operation which can reduce the computational complexity and use two thresholds to detect the frame starting point and the value of phase ambiguity simultaneously. The parallel architecture of frame synchronizer which can simultaneously perform phase ambiguity resolution has been designed for high data rate systems. From the results of the simulation, we make the conclusion that it can work effectively as we expected.
