以提高自适应帧长高级在轨系统(AOS)的帧同步性能为目的,提出一种综合考虑与信道误码有关的虚漏概率和与附加同步标记(ASM)码型有关的虚警概率来实现帧同步的综合帧同步方案.分析推导并仿真验证了综合帧同步性能公式,得出相应的帧同步仿真参数.最后,对综合帧同步方案和已有的基本帧同步方案的帧同步性能进行仿真比较.结果表明,综合帧同步方案的帧同步性能明显优于基本帧同步方案.
In order to improve the frame synchronization performance of advanced on-orbit system (AOS) with adaptive frame length, this paper proposes a method which considers the probability of false alarm and false alarm probability associated with ASM pattern Frame synchronization.Analyzing and deducing and simulating and verifying the formula of the integrated frame synchronization performance, the corresponding frame synchronization simulation parameters are obtained.Finally, the frame synchronization performance of the integrated frame synchronization scheme and the existing basic frame synchronization scheme Simulation results show that the frame synchronization performance of the integrated frame synchronization scheme is obviously better than that of the basic frame synchronization scheme.
