摘要
在ADSL在线测试系统设计中,接收器的同步问题是设计的难点之一。本文论述了ADSL在线测试系统的三种同步技术(采样同步,帧同步和超帧同步),对同步算法进行了理论分析,并给出了基于FPGA硬件的同步实现方案。
The synchronization problem of the receiver is one of the difficulties in designing the ADSL on-line test system. This paper discusses the three kind of synchronization technologies （sample synchronization, ADSL frame synchronization and superframe synchronization） used in ADSL on-line test system, and analyses the synchronization algorithm in theory. The synchronization designed method based on FPGA hardware is provided.
