本文针对自同步扰乱序列产生的误码扩散,设计并实现了可以用于传输高速率和高稳定度数据的同步帧头检测器,内容包括对数字信号在解扰过程中造成的误码扩散程度及其给同步帧头检测所带来影响的分析以及同步帧头检测器的具体实现,该设计在一定程度上解决了在猝发数据实时传输的过程中,解扰时出现误码扩散的情况下,接收端无法检测出数据中的同步帧头,造成数据丢失,以及简单的帧头检测电路无法满足高速数据传输过程中瞬时运算量过大的问题。

In order to slove the error spread generated from the self-synchronization descrambling,A design of detection of frame synchronization can be used to transmit High-speed rate and high stable data is proposed.It includes the analysis of the error spread level of digital signal generated from the descrambling and the impact it brought to the synchronization of frame detection and the Realization of the design.To some degree,it solved the problem of the loss of data caused by the receiver can＇t detect data of synchronous frame head when error spread happened in real-time transfer process,and the simple detection can＇t satisfy the instantaneous excessive computational cost in high-speed data transmission process.
