一种实用的IS-95基站接收机介绍

An Introduction to a Practical Base Station Receiver of IS-95

针对联通即将推出的CDMA系统,介绍了一种实用的IS-95基站接收机方案,包括系统的整体结构,各模块的原理及具体实现方案等部分,并对关键模块在典型的信道模型下进行性能仿真,比较得出性能、硬件量比最佳的实现方案。该接收机成功支持多移动台同时通信。

Concerning the CDMA communication system being about toused by China UNICOM, a practical base station receiver method of IS-95 was introduced in this paper, including the structure of the system, the principle ofevery module and their detail realization methods. The performances of modules were simulated under typical channel model. The best realization method in rate of function to amount of hardware was got. The receiver can successfully supportmulti-mobile station .
