【摘要】：移动通信作为当今迅猛发展的一项技术,它让人类的生活发生了翻天覆地的改变。从最初的电话通信到移动通信,再到未来的点到点通信,移动通信在短短三十年的发展堪称一次科技革命。正当我们还在感叹3G给我们带来的便利时,下一代移动通信标准LTE已经进入商用。国际上虽然大多数国家都采用FDD-LTE模式,但其必须采用成对频率,而对于TD-LTE其上下行链路在同一频率上工作,通过断续的时隙发送用户数据,其适合传输非对称数据业务,并能有效利用零散频段,在频谱资源紧缺的信息时代,TD-LTE模式在未来移动通信中将有不可替代的地位,研究和发展TD-LTE无线网络的规划与设计具有重要的意义。本文对TD-LTE无线网络规划进行了研究分析并对辅助平台进行了设计,论文的主要工作有：1、对TD-LTE系统进行了研究,同时对无线网络规划进行了设计；2、对网络规划辅助平台进行了设计与实现；3、利用本文所设计的辅助平台对成都宽窄巷子TD-LTE无线网络进行规划；4、对成都宽窄巷子TD-LTE无线网络进行测试并获得较好效果。其中本网络规划辅助平台主要运用了GIS与MFC框架语言对系统进行实现。该网络规划辅助平台能够简便高效的进行网络规划,其中主要包括平台登录、用户管理、工程建立与管理、规划区块的导入与管理、基站建设与管理以及参数设置与信息覆盖六大模块。同时运用所设计的辅助平台,对成都宽窄巷子TD-LTE无线网络进行了规划,包括TD-LTE网络规划与仿真,并对仿真结果进行了分析,从而再对TD-LTE无线网络进行了方案优化。通过对无线网络的DT与CQT测试,我们获得了网络规划效果参数,经过分析与对比显示,本次TD-LTE无线网络规划达到了初步的成功,获得了下载20.75Mbps与上传16.61Mbps的平均速度。
[Abstract]:As a rapidly developing technology, mobile communication has changed human life dramatically. From the initial telephone communication to the mobile communication, and then to the future point to point communication, the development of mobile communication in just 30 years can be regarded as a technological revolution. Just as we are still bemoaning the convenience of 3G, the next generation mobile communication standard, LTE, has come into commercial use. Although most countries in the world adopt FDD-LTE mode, it must adopt pair frequency, but for TD-LTE, its uplink and downlink work on the same frequency and transmit user data through intermittent time slots, which is suitable for transmitting asymmetric data service. The TD-LTE mode will play an irreplaceable role in the future mobile communication in the information age where spectrum resources are scarce. It is of great significance to research and develop the planning and design of TD-LTE wireless network. In this paper, the TD-LTE wireless network planning is studied and analyzed, and the auxiliary platform is designed. The main work of this paper is: 1. The TD-LTE system is studied. At the same time, the wireless network planning is designed, and the auxiliary platform of network planning is designed and implemented. Using the auxiliary platform designed in this paper, the TD-LTE wireless network of Chengdu wide narrow alley is planned. The TD-LTE of Chengdu wide narrow alley is designed. The wireless network is tested and good results are obtained. The network planning assistant platform mainly uses GIS and MFC framework language to implement the system. The network planning assistant platform can easily and efficiently carry out network planning, which mainly includes platform login, user management, project establishment and management, and the introduction and management of planning blocks. Base station construction and management, parameter setting and information coverage six modules. At the same time, using the designed auxiliary platform, the TD-LTE wireless network of Chengdu wide narrow alley is planned, including TD-LTE network planning and simulation, and the simulation results are analyzed, and then the scheme of TD-LTE wireless network is optimized. By testing the DT and CQT of wireless network, we get the parameters of network planning effect. The analysis and comparison show that the TD-LTE wireless network planning has achieved initial success, and the average speed of downloading 20.75Mbps and uploading 16.61Mbps has been obtained.
