TD-SCDMA作为中国提出的第三代移动通信标准,中文含义为时分同步码分多址接入,是ITU(国际电联)正式发布的第三代移动通信空间接口技术规范之一,它是第一个由中国提出的,以我国知识产权为主的、被国际上广泛接受和认可的无线通信国际标准,已经成为我国电信史上重要的里程碑。TD-SCDM技术采用了智能天线、联合检测、同步CDMA、软件无线电、低码片速率、多时隙、可变扩频系、自适应功率调整等先进技术。3G固话接入终端实现了普通电话机的接入功能,用户可以通过普通电话机使用TD无线固话业务。文章简绍了移动通信技术的演进发展,对具有中国知识产权的TD-SCDMAA移动网络技术进行了阐述,分析目前运营的TD无线固话终端技术,对所应用的环境场景进行了探讨。
As the third generation mobile communication standard put forward by China, TD-SCDMA refers to time-division-synchronous code division multiple access in Chinese and is one of the technical specifications of the third generation mobile communication space interface formally released by ITU (ITU). It is The first international standard of wireless communications proposed by China, mainly based on our country’s intellectual property rights, has been widely accepted and accepted internationally. It has become an important milestone in the history of telecommunications in our country. TD-SCDM technology uses advanced technologies such as smart antennas, joint detection, synchronous CDMA, software radio, low chip rate, multiple time slots, variable spreading systems and adaptive power adjustment. 3G fixed access terminal to achieve the normal telephone access capabilities, users can use ordinary telephone TD fixed-line business. This paper introduces the evolution of mobile communication technology, expounds the TD-SCDMAA mobile network technology with Chinese intellectual property, analyzes the currently operating TD wireless fixed-line terminal technology, and discusses the applied environment scenarios.
