TD-SCDMA技术正在大规模的应用,发展迅速;TD-LTE技术作为TD-SCDMA的未来演进技术各项规范正在逐步完善,测试正在逐步开展,文中对TD-LTE(TDD LTE)的演进过程,网络架构,物理层关键技术,高层协议栈进行了初步分析介绍,并对照TD-SCDMA系统,对TDD双工方式、OFDM技术,MIMO技术和智能天线的应用,协议非接入层进行的改进和发展进行了介绍;最后文章对TD-LTE的发展进行了探讨。
TD-SCDMA technology is being applied on a large scale and is developing rapidly. The specifications of TD-LTE technology as the future evolution technology of TD-SCDMA are gradually being improved and the testing is being carried out step by step. The evolution of TD-LTE (TDD LTE) Network architecture, the key technologies of the physical layer and the high-level protocol stack, and compared with the TD-SCDMA system, the improvement of the protocol non-access layer and the application of TDD duplex mode, OFDM technology, MIMO technology and smart antenna, The development has carried on the introduction; The last article has carried on the discussion to the development of TD-LTE.
