| 摘 要： | 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。

| Abstract: | frame synchronizer of variable rate and variable frame length using parallel correlative technique is introduced in this paper. Major frame and subframe are synchronized by using the combining method of hardware and software based on 8031 microprocessor. According to theoretical calculation, error threshold, check frame number a and protection frame number 5 are obtained. The frame synchronizer was used successfully in receiving communication satellite PCM telemetry data. |
