摘要
以提高AOS的系统吞吐量为目的,提出了AOS自适应帧长传输的系统模型,改进了AOS空间数据链路协议的传输帧格式,设计了一种适用于新系统的帧同步方案,推导并分析了帧同步性能公式,得出帧同步仿真参数。在此基础上,对新系统的吞吐量性能进行了仿真。结果表明与AOS固定帧长传输系统相比,AOS自适应帧长传输系统的吞吐量得到了有效地提高,证明了所提出的新系统及改进的AOS传输帧格式和帧同步方案的有效性。
In order to improve the throughput of AOS,a model of AOS adaptive frame length transmission system was proposed.Specifically,in this model,the framework of transfer frame in AOS Space Data Link Protocol was redefined,and a scheme about frame synchronization was designed.Then the performance formula of frame synchronization was given and analyzed to obtain the synchronization parameters used in the later simulation.At last,based on those,the throughput of the proposed system was simulated.Simulations show compared with fixed frame length transmission system,the throughput of AOS adaptive frame length transmission system can be improved effectively.So the redefined framework of AOS transfer frame and the frame synchronization scheme of the presented system are valid.
