| 摘 要： | 针对时分长期演进系统部署资源紧张的问题,设计一种时分长期演进候选频段分析系统。通过对四个典型城市(西安、北京、南京、上海)的频谱使用情况进行测量,将测量数据建立数据库,借助GIS软件将测量数据以频谱地图的形式进行展示,同时通过程序计算出各个频段的频谱占用度,并在特高频等频段中查找可利用的空闲频谱资源从而判断其是否能够部署时分长期演进系统。最后以西安为例进行了运算分析,结果表明,在西安市郊区698806MHz存在一定空闲频段能够部署时分长期演进系统。

| Abstract: | A TD-LTE Spectrum Analysis System is designed in this paper for the problem of the lack of frequency resources in our country in the TD-LTE system deployment.Based on the spectrum measurement in the four typical cities （Xi ’an,Beijing,Nanjing,Shanghai ）,a database is established to store the measured data.The measured data is showed in the form of the spectrum map through the GIS software and the spectrum occupancy for every frequency channel is calculated.Idle spectrum resources are searched in the UHF （Ultra High Frequency）to find any available frequency in order to determine whether to deploy TD-LTE system there.Xi’an is chose as an example for the operational analysis.The analysis result shows that there are some idle frequency band in 698～806 MHz from Xi’an suburb which can be used to deploy TD-LTE system. |
