LTE(Long Term Evolution)是第四代移动通信的主流技术之一,TD-LTE是时分双工模式的LTE系统,以正交频分复用(OFDM)和多输入多输出(MIMO)技术为基础,本文主要介绍TD-LTE技术的原理及关键技术。
LTE (Long Term Evolution) is one of the mainstream technologies of the fourth generation of mobile communications. The TD-LTE is an LTE system in a time division duplex mode. The LTE system is based on orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO) Fundamentals, this paper introduces the principle and key technologies of TD-LTE technology.
