【摘要】 通过对CCSDS AOS协议的研究,指出影响AOS协议包业务吞吐量的因素,并分析采用可变帧长、固定帧长以及在不同误码率情况下使用不同帧长度的最优帧长方案对帧同步精度及系统吞吐量的影响.仿真结果表明,固定帧长方案比可变帧长方案能获得更高的正确同步概率和吞吐量,而当误码率小于某一门限值时,最优帧长方案可以在不降低正确同步概率的情况下,获得更高的吞吐量.更多还原

【Abstract】 By study on the knowledge of CCSDS AOS protocol,the factors affecting the throughput are given.The impact of framing schemes using fixed length frames,variable length frames and optimal length frames on the probability of correct frame synchronization and the throughput is analyzed.Simulation results show that the fixed length framing sheme can provide higer correct probability of frame synchronization than that of the variable length framing scheme,and when the BER value is lower than a certain number,the optimal length framing sheme can provide higher throughput than that of the fixed length framing scheme,without reducing the probability of correct frame synchronization.更多还原
