【摘要】：LTE是由3GPP(3rd Generation Partnership Project)组织提出的新一代移动通信系统,是第三代移动通信的主流演进技术之一。LTE系统中定义了时分双工(TDD, Time Division Duplexing)和频分双工(FDD, Frequency Division Duplexing)两种双工方式,其中采用时分双工的TD-LTE(即LTE TDD)是具有我国自主知识产权的TD-SCDMA系统的后续演进。TD-LTE得到了中国政府以及全球大部分运营商和系统设备制造商的高度关注与支持。2013年末,国内的三家运营商获发了“LTE／第四代数字蜂窝移动通信业务(TD-LTE)"经营许可。其中,中国移动已率先在中国大陆开展商用。终端设备是移动通信系统中的核心组成部分,其射频性能和质量在商用化进程中起着至关重要的作用。而目前TD-LTE的在技术成熟度和商用经验方面还存在着不少欠缺,仍需要大量的终端测试工作保证其商用成功。设计和开发出高效便捷的射频一致性测试仪对提高TD-LTE终端设备的射频性能和质量、推动我国仪表产业的发展,具有十分重要的意义。本文首先回顾了移动通信的发展历程,介绍了LTE标准和其关键技术,讨论了终端射频一致性测试的技术指标与测试方法,对射频一致性测试仪的整体结构进行了研究。重点设计了测试仪的主控软件,包括界面显示模块、按键处理模块、远程控制模块等。为TD-LTE射频一致性测试仪的软件设计提出了一个高效便捷、界面友好的解决方案。
[Abstract]:LTE is a new generation mobile communication system proposed by 3GPP 3rd Generation Partnership Project. It is one of the mainstream evolution technologies of the third generation mobile communication. It defines two kinds of duplex modes: time division duplex (TDD) and frequency division duplex (FDD) and Frequency Division Duplexing (FDD) in the third generation mobile communication system. TD-LTE (LTE TDDD), which uses time division duplex (TD-LTE), is a follow-up evolution of TD-SCDMA system with independent intellectual property rights in China. TD-LTE has been highly concerned and supported by the Chinese government and most operators and system equipment manufacturers in the world. Three domestic operators have been granted the license of "LTE/ 4th Generation Digital Cellular Mobile Service". Among them, China Mobile has taken the lead in commercial use in mainland China. Terminal equipment is the core component of mobile communication system. Its RF performance and quality play an important role in the process of commercialization. However, there are still many deficiencies in the technical maturity and commercial experience of TD-LTE. Still need a lot of terminal testing work to ensure its commercial success. The design and development of an efficient and convenient RF consistency tester will improve the RF performance and quality of TD-LTE terminal equipment, and promote the development of the instrument industry in China. This paper first reviews the development of mobile communication, introduces the LTE standard and its key technologies, and discusses the technical specifications and testing methods of terminal RF conformance testing. The overall structure of the RF consistency tester is studied. The main control software of the tester is designed, including the interface display module, the key processing module. Remote control module and so on. For the software design of TD-LTE RF conformance tester, this paper presents an efficient and convenient solution with friendly interface.
