| 摘要: |
| 针对传统D触发器帧同步方案可靠性的缺陷,通过在同步检测模块中应用容差技术、在保护电路中采样自适应技术,提出一种自适应快速搜捕帧同步器设计方案,该方案可根据误码率的大小自动调节帧同步器内保护参数,使确定同步、失步时间均缩短一个帧周期,搜捕时间也缩短了一个帧周期. |

| Abstract: |
| In allusion to the defect of reliability of the frame synchronous scheme with D - triggers, by applying error- tolerant technology to detective module and adaptive technology to protective module, a new approach of the fast adaptive searching frame synchronization scheme is presented. This system can auto- matically adjust protective parameter of frame synchronizer, and it makes the time of assuring synchronization and non - synchronization shorten one period of frame, as well as the searching time. |
