TD-SCDMA无线网络优化方法研究

摘 要

在我国，目前已经拥有了全球最大的移动通信网和最大的移动用户数，移动用户的数量已经超过4亿，而且这个数字还将快速增长。现有的第二代移动通信系统无论是在频谱资源，还是在所能提供的业务方面，都已经不能满足移动通信用户的需求。

本文所讨论的TD-SCDMA是一项完全由我国自主研究的3G技术，论文中将从TD-SCDMA与其他移动通信系统间的干扰及协调这几个方面来进行讨论。其中对于覆盖和容量规划将在理论方法上进行较为详细地论述；而与其它系统间的干扰问题将通过信令、无线网络规划流程、覆盖和容量规划、以及TD-干扰分析来进行。

在文章的最后，将通过对自己亲身参与的部分规划工作的叙述来对本论文做一个结束，这个也是本论文中对于自己在实践中所学比较全面的总结。

关键词：TD-SCDMA，覆盖规划，容量规划，干扰分析

TD-SCDMA wireless network optimization method

Abstract

In China, now has the world's largest mobile communications network and the

largest number of mobile users, the number of mobile users has more than 400 million, and this number will grow rapidly. Existing second generation mobile communication systems, both in the spectrum, or can offer the business, are no longer meet the needs of mobile users.

Discussed in this paper TD-SCDMA is a completely independent study of China's 3G technology, TD-SCDMA from paper and other mobile communication systems and coordination between the interference in these areas to be discussed. One for the coverage and capacity planning will be carried out in the theoretical methods discussed in detail; and interference with other systems issues will be through signaling, wireless network planning process, coverage and capacity planning, and analysis for TD-interference.

At the end, through participation on the part of his personal narrative planning to make an end of the paper, this is also the thesis is their occasional Shijian in Suoxue the Zongjie more comprehensive.

Key words: TD-SCDMA, coverage planning, capacity planning, interference analysis
