| 摘 要： | 为提高高级在轨系统（AOS）中数据传输的可靠性,对AOS帧同步技术进行研究。在分析了帧同步状态转移过程中可能出现的漏检现象与虚警现象的基础上,采用经典Z变换方法,研究了选取不同长度的附加帧同步标记、前方保护时间和后方保护时间对帧同步入锁时间、误锁概率、误锁后最快解锁概率和帧同步保持时间等重要性能参数的影响,并给出了仿真结果。最后给出了不同误码率下AOS帧同步参数选取的建议值,为实际应用提供参考.

| Abstract: | Frame synchronization method is studied to enhance the reliability of AOS data transmission. On the basis of analyzing the phenomenon of false alarm and failed detection,the effects of choosing various length of ASM,front protection time and rear protection time on synchronization locking time,false locking probability,fastest unlocking probability after false locking and frame synchronization holding time are pointed out. Simulations are also performed to verify these results. At last the recommended parameters of AOS frame synchronization system under different BER conditions are presented,which can provide reference for practical application. |
