本文讨论了数字通信中一种具有长保持时间的新型帧同步系统,并与传统帧同步系统进行了比较。结果表明,在两个系统结构参数——校核次数α及保护次数β相同条件下,新系统平均失帧时间与传统系统基本相同,而平均同步保持时间增大了许多个数量级,因而特别适合于变参信道或高误码率条件下工作。
This paper discusses a new type of frame synchronization system with long hold time in digital communications, which is compared with the traditional frame synchronization system. The results show that the average frame loss time of the new system is basically the same as that of the traditional system under the same conditions of the two system structure parameters - check number α and the number of protection times β, while the average synchronization hold time increases by many orders of magnitude, which makes it particularly suitable In variable channel or high bit error rate conditions.
