| 摘 要： | 针对星地链路的快速建立问题，提出一种星地通信链路的快速建立方法，设计建链数据帧格式，并给出星地链路建立条件下伪随机序列长度设计的基本原则。对建链概率和建链时间进行数学建模，仿真结果表明，在建链时间和传输时间近似相等的情况下，当信噪比为?20 dB时该方法可获得接近1的建链概率。

| Abstract: | Aiming at the problem of quickly establishing links between satellite and ground,a new method of fast links establishment is proposed,link establishment data frame format is designed,and the basic principles of pseudo-random length is given.In this paper,the mathematical model of link establishment probability and link establishment time is built,and the link establishment modes are repetitiously simulated.Simulation results demonstrate that under the precondition of guaranteeing link establishment time analogous to transmission time,with the SNR of ？20 dB,link establishment probability is close to 1. |
