摘　　要：低轨卫星通信系统有着延时高和频偏大的信道特征,使得其与5G随机接入技术并不能直接融合。针对这个问题,以5G随机接入前导序信号格式为基础,对低轨卫星移动通信系统的随机接入技术进行分析和研究。Low-orbit satellite communication system has the channel characteristics of high delay and high frequency bias,which makes it unable to directly integrate with 5G random access technology.To solve this problem,based on the 5G random access leading sequence signal format,the random access technology of low-orbit satellite mobile communication system is analyzed and studied.

关 键 词：5G 随机接入技术 低轨卫星 移动通信技术
