介绍了一种采用并行相关技术实现的可变速率、可变帧长的帧同步器。它以８０３１单片机为基础采用硬件、软件相结合的方法实现主帧、副帧同步。并根据理论计算，得出容错门限、校核帧数。和保护帧数卢。该帧同步器已成功地运用于中国通信卫星ＤＦＨ－３在主动轨道段和过渡轨道段遥测数据的解调。
A frame synchronizer with variable rate and variable frame length is introduced in this paper. It based on the 8031 single-chip hardware and software to achieve the main frame, the sub-frame synchronization. And according to the theoretical calculation, draw the fault-tolerant threshold, check the number of frames. And protect the frame number Lu. The frame synchronizer has been successfully applied to the demodulation of telemetry data of the China telecom satellite DFH-3 on the active orbit segment.
