【摘要】：随着移动无线通信业的发展和移动互联对无线传输速度的需要,新一代通信制式的出现是必然的趋势,由3GPP制定的TD-LTE (Time Division Long Term Evolution)是使用广泛的向4G通信演进的技术之一。将LTE通信技术应用到芯片生产之前,对该技术进行算法上的验证是必要的。验证的方法有很多种,但是由于使用虚拟仪器验证具有实现成本低,显示效果直观,调试方便等优势,本文采用了用虚拟仪器来验证通信协议算法。本文源于项目《LTE矢量信号收发机的开发》,项目基于虚拟仪器搭建了一个通信系统,分为矢量信号发送机和接收机,本文的工作重点在矢量信号发送端的下行链路的信道处理过程的研究和资源映射的算法实现。文中首先介绍了移动无线通信的发展历史和LTE出现的背景,其次介绍了LabVIEW编程工具和虚拟仪器的基本概念,然后详细描述了3GPP36.211通信协议物理层的工作流程原理,对下行链路的资源映射算法进行了深入的研究,并基于LabVIEW编程工具对每个信道的资源映射设计方法做了详细的描述,最后对程序进行了测试,得出结果证实了每个模块的可靠性。虚拟仪器具有开发维护费用低、技术更新周期短、开放性模块可重复性使用等特点,根据本论文的设计思路开发出的模块可以直接在虚拟仪器的平台上进行验证,在模块的开发中保证了功能的完整性和配置参数的完整性,在后续技术更新中,本模块可以不经过修改直接使用,大大缩短了开发的时间。
[Abstract]:With the development of mobile wireless communication industry and the need of mobile interconnection for wireless transmission speed, the emergence of a new generation of communication standards is an inevitable trend. The TD-LTE time Division Long Term evolution developed by 3GPP is one of the widely used technologies to evolve to 4G communication. Before applying LTE communication technology to chip production, it is necessary to verify the algorithm of this technology. There are many kinds of verification methods, but because the use of virtual instrument verification has the advantages of low cost, visual display effect, convenient debugging and so on, this paper uses virtual instrument to verify the communication protocol algorithm. This paper derives from the project "the Development of LTE Vector signal Transceiver". The project builds a communication system based on virtual instrument, which is divided into vector signal transmitter and receiver. This paper focuses on the research of downlink channel processing of vector signal transmitter and the implementation of resource mapping algorithm. This paper first introduces the history of mobile wireless communication and the background of LTE, then introduces the basic concepts of LabVIEW programming tools and virtual instruments, and then describes the principle of the physical layer of 3GPP36.211 communication protocol in detail. The downlink resource mapping algorithm is deeply studied, and the design method of resource mapping for each channel is described in detail based on LabVIEW programming tools. Finally, the program is tested. The results confirm the reliability of each module. Virtual instrument has the characteristics of low cost of development and maintenance, short period of technology update, repeatable use of open module, etc. According to the design idea of this paper, the module developed by this paper can be directly verified on the platform of virtual instrument. In the development of the module, the integrity of function and the integrity of configuration parameters are guaranteed. In the subsequent technical update, the module can be used directly without modification, which greatly reduces the development time.
