3G移动通信系统中基于TD-SCDMA传播模型的研究
|
摘要
作为我国对国际上第三代移动通信的贡献，我国提出的TD-SCDMA RTT建议，通过一年多的完善和融合，已经成为ITUIMT-RSPC(TG-8／1 输出文件)的一个组成部分。在本文中，在对第三代移动通信中TD-SCDMA RTT作一个简单的介绍同时，著重讨论TD-SCDMA系统的传播模型的选取及校正、网络规划等相应理论。
本论文首先论述了TD-SCDMA系统的物理层传输技术及与3G另一标准UTRA TDD在物理层参数和特性比较。论述了无线电波传播模型的概念和作用。利用MATLAB软件对各种传统传播模型进行仿真，得出仿真结果并建立传播模型初步概念。论证了TD-SCDMA传播模型应用软件整体方案，利用Delphi软件编写了具有校正功能和实时计算传播衰耗值功能(与GPS系统配合)的应用软件。论文从理论的角度分析了TD-SCDMA网络的规划理论，主要从网络拓扑结构、上下行链路功率平衡预算报告、有效通信距离的估算、上下形链路干扰的分析和系统最大容量分析五个方面进行了论述。
该论文基本达到了预计的目标，可为TD-SCDMA系统传播模型的研究提供一个软件试验平台。
As our country's contribution to the international communication domain,the TD-SCDMA RTT specification that was proposed by our country has been improved and integrated by more one year.The TD-SCDMA RTT specification had been a part of the ITU IMT-RSPC.In this paper,the first part is the introduction of the TD-SCDMA RTT,the second part is the theory about the choice and the revisment of the TD-SCDMA propagation model,the last part is the discussion about the TD-SCDMA network planning theory.
Firstly,this paper shows the outline of the TD-SCDMA system physical layer transmission technology.In the physical layer parameters' aspects,the paper maks the difference between the TD-SCDMA and the other specification --UTRA TDD.The paper discourses upon the concept and function of the radio propagation model.By the MATLAB software,all kinds of the propagation models are simulated.Using the simulation result,we can set up the basic concept of the propagation model.
The paper demonstrates the whole plan of the propagation model application software.With the Delphi software, an application software including the function of the realtime calculating path loss value is compiled completely.The paper analyses the planning theory of the TD-SCDMA network.Its main aspects include the
backbone of the network,the link budget report,the budget of the effective distance,the analyse of the link interference and the analyse of the system capacity.
