On the other hand, 4G also because of its high speed of data transmission, high-speed dialogue working alliance known as machine between fully deserve "". This paper briefly analyses: (1) work structure of 4G; (2) the key technology such as OFDM, 4G, software radio, smart antenna technology, MIMO technology. (3) comparison of different indicators of 3G and 4G, analyzes the different techniques of 3G and 4G use. (4) discusses the present situation and development of 4G. keywords : 4G, munication 4G 网络通信新技术研究 3 目录 4G 网络技术介绍..................................................................................................................................... 2 摘要.......................................................................................................................................................... 2 Abstract .................................................................................................................................................... 2 前言.......................................................................................................................................................... 4 第一章 4G 简介....................................................................................................................................... 4 第二章 4G 系统网络结构.
