CDMA通信系统网络优化
摘要:CDMA(Code Division Multiple Access)码分多址是在数字技术的分支——扩频通信技术基础上发展起来的一种崭新而成熟的无线通信技术。CDMA通信系统具有扩频通信系统的特点,抗干扰性强,频谱利用率高,容量大。它是第三代移动通信系统的主要空中接口技术。移动通信网是一个不断变化的网络,因此需要对网络不断进行优化以适应各种变化,排除网络中不断出现的各种故障,优化网络资源配置,改善网络运行性能,提高服务质量,从而使网络始终处于最佳的运行状态。
本文对 CDMA 无线网络的优化技术的概况和发展趋势,网络优化中常见的问题进行研究,并提出了一些优化调整措施和参数配置的建议。
本文主要内容分为:
1、介绍CDMA通信原理及技术
2、介绍CDMA通信系统网络优化在国内外的现状,及其网络优化的意义。
3、研究CDMA 无线网络故障的分析,针对干扰问题、接入失败、掉话问题等几种典型的无线通信网络故障问题进行具体的分析,从而得到一些CDMA网络优化方面的解决方案,最终达到提高CDMA通信系统网络质量的要求。

Network optimization munication system
Abstract: CDMA(Code Division Multiple Access)is a digital technology in the branch - spread munications technology developed on the basis of a new and sophisticated munications technology. munication system with spread munication system is characterized by strong anti-interference, spectrum efficiency, high-capacity. It is the third generation munication system, the main air interface technology. work is a constantly work, so the need for ongoing optimization of work to adapt to changes, exclude a variety of work failure, work resources, improve the performance work operations, improve service quality, so that work always in the best state of operation.
In this paper, CDMA work optimization technology, progress and development trend, mon problem work optimization studies, and made some adjustments and parameters to optimize the configuration of the proposal.
This paper is divided into:
1, the introduction of munication theory and technology
2, network optimization munication system described in the status quo at home and abroad, and the significance work optimization.
3, of CDMA work fault analysis for interference, the access fails, the problem of dropped calls and other types of typical work problems that are specific analysis to get some of the work optimization solutions, and ultimately to improve municatio
