LA-CDMA蜂窝移动通信系统的无线定位技术

讨论了蜂窝移动通信系统中无线定位技术在智能交通系统(ITS)中的应用.特别针对了在我国具有自主知识产权的第三代移动通信系统,LA-CDMA系统中附加无线定位功能的原理与方法,提出了在正向链路和反向链路中分别实现定位服务方法,并指出各自的优点和缺点,同时分析了在CDMA蜂窝网络中定位所遇到的各种问题.

Radiolocation Technology in LA-CDMA Wireless Cellular Network

Applications by the radiolocation technology in a code division multiple access (CDMA) wireless cellular network are discussed, especially was used to manage fleet and vehicles in an Intelligent Traffic System (ITS) . In the LA CDMA wireless communication system, a third generation communication system, which was invented by Chinese and has Independent Intelligent Property (IIP), the principle and methods for an additional radiolocation service are given. We propose two ways to implement it ,one is by the forward link, the other is by the reverse link, the advantages and disadvantages are also compared for each other in this article. We also analyze the problems that are encountered when using LA CDMA cellular networks for position.
