PAGE 无线通信技术热点及其发展趋势 摘要 我国的无线通信产业通过短短几十年的发展，已经发展到第三代和第四代移动通信技术，多种无线通信技术都得到了广泛的应用。目前，无线通信领域主要包括3G、TD-LTE-Advanced、UWB、Wi-Fi、RFID等几大技术热点。本文首先介绍了无线通信技术的发展历程和特点，然后主要针对我国具有自主知识产权的TD-LTE-Advanced技术的产生及其特点进行了简要的分析。 TD-LTE-Advanced作为TD-SCDMA技术的演进，是下一代移动通信系统IMT-Advanced 的两大技术之一。与第三代移动通信系统采用CDMA技术不同，TD-LTE采用OFDM和MIMO作为基本技术，大量采用了目前移动通信领域最先进的技术和设计理念。 关键词：无线通信，3G，LTE，TD-LTE-Advanced Hot Spots in Wireless Communication Technology and its Tendency of Development Abstract By only a few decades of development,the wireless industry in China has grown to the third and the fourth generation mobile communication technology and a variety of wireless communication technology have been widely used. At present, the hot spots in wireless communication technology is mainly include 3G, TD-LTE-Advanced, UWB, Wi-Fi, RFID,etc.This paper first introduces the development history of wireless communication technology and its characteristics,then it briefly analyse the development process and features of TD-LTE-Advanced,and our country has independent intellectual property rights for this technology. As the evolution of TD-SCDMA Technology, TD-LTE-Advanced is one of the two candidates for next generation mobile communication system (IMT-Advanced). Compared with CDMA technology which is widely adopted by 3G system, TD-LTE introduces OFDM and MIMO as technical basis,together with many state of art advanced technologies and designs.
