【摘要】：TD-LTE是我国具有自主知识产权的移动通信系统,目前很多国家都在使用TD-LTE系统,我国香港也即将于2012年底商用TD-LTE。作为第四代移动通信系统之一,TD-LTE的演进技术—TD-LTE-Advanced的研究进展在全球范围内受到重视。终端射频一致性测试是衡量终端性能的关键技术,是验证终端指标达到商用水平的权威手段。根据TD-SCDMA和TD-LTE的商用化进程,终端产品在投入市场之前,需要经过反复的测试来验证和提高产品性能。终端射频一致性测试不仅有利于产品性能的提高,还可以推动技术的发展和完善。本论文旨在利用市场上流行的TD-LTE系统模拟器、频谱仪、信号源、微波源等仪表,研发我国独立自主知识产权的TD-LTE-ARIO系统的终端射频一致性测试系统。本文的研究点主要集中在TD-LTE-A测试技术研究和测试系统的硬件与软件的设计与实现。首先介绍课题的研究背景、课题来源和意义；详细介绍影响TD-LTE-A终端射频指标的载波聚合技术和增强型多天线技术,在此基础上分析这两种技术在终端测试中的测试思路,进而提出载波聚合和上行多天线技术的测试方法和测试原理图。针对一致性测试系统的开发,论文从硬件和软件两方面进行了详细研究。硬件部分主要包括系统总体设计、硬件设计模型、系统硬件设计与硬件设计验证四部分；软件部分主要包括系统软件概述、模块设计、仪表控制模块的编码与实现、测试例模块的编码与实现与系统设计评估。系统硬件设计保证了测试例运行的硬件环境,软件设计实现了测试系统初步的自动化。最后总结论文内容,计划下一步研究工作。
[Abstract]:TD-LTE is a mobile communication system with independent intellectual property rights in our country. At present, many countries are using TD-LTE system. In end of 2012, commercial TD-LTE. as one of the 4th generation mobile communication systems, TD-LTE-Advanced, the evolution technology of TD-LTE, will be paid more attention to in the world. Terminal RF conformance testing is the key technology to measure the terminal performance and the authoritative means to verify that the terminal index reaches the commercial level. According to the commercial process of TD-SCDMA and TD-LTE, the terminal product is put into the market before it is put into the market. It is necessary to verify and improve the product performance through repeated tests. The terminal RF conformance test is not only conducive to the improvement of product performance, but also can promote the development and improvement of technology. This paper aims to utilize the popular TD-LTE system simulator in the market. Spectrometer, signal source, microwave source and so on, develop the terminal radio frequency consistency test system of TD-LTE-ARIO system with independent intellectual property in our country. This paper mainly focuses on the research of TD-LTE-A test technology and the design and implementation of hardware and software of the test system. Firstly, the research background, source and significance of the subject are introduced. This paper introduces the carrier aggregation technology and enhanced multi-antenna technology which affect the radio frequency index of TD-LTE-A terminal in detail. On this basis, the testing ideas of these two technologies in terminal test are analyzed. Furthermore, the test method and test schematic diagram of carrier convergence and uplink multi-antenna technology are presented. For the development of conformance test system, the hardware and software are studied in detail. The hardware part mainly includes the overall design of the system. The hardware design model, the system hardware design and the hardware design verification, the software part mainly includes the system software outline, the module design, the instrument control module code and the realization, The hardware design of the system ensures the hardware environment of the test case, and the software design realizes the preliminary automation of the test system. Finally, the content of the paper is summarized and the next research work is planned.
