本文通过对TD-LTE移动通信技术的论述,结合高铁在高速运动环境下引起的快速信道衰落、快速切换、多普勒频移加剧等特点,提出了TD-LTE系统分布式基站多RRU解决方案,并进行论证分析。
Based on the discussion of TD-LTE mobile communication technology and the characteristics of fast channel fading, fast switching and Doppler shift caused by high-speed railway in high-speed environment, this paper proposes a solution of multi-RRU for distributed base station in TD-LTE system , And demonstration analysis.
