摘要
做为新一代的移动通信系统,TD-LTE的随机接入较2G/3G系统有更为精细的设计要求,为了使高速铁路中的TDLTE网络能更稳定地运行,从Preamble、根序列和N_(CS)等方面着手分析,总结出了一套适合中国高铁的TD-LTE PRACH参数体系,并对其进行了验证,验证得到了良好的效果。
As the new generation of mobile communication system, the random access in TD-LTE has higher design requirements than 2G/3G systems. In order to guarantee the stability of TD-LTE network in high-speed railway, a set of TD-LTE PRACH parameters suitable for high-speed railway of China was summarized according to preamble, root sequence and Ncs, and then these parameters were verifi ed by the good effect.
