GSM900/DCS1800双频段基站测试系统的硬件设计

摘要

为了进行基站的灵敏度测试，对移动通信系统运营进行维护，该项目实现了 GSM900和 DCS1800双频段便携式基站测试系统的设计。基站测试系统硬件由信号处理与控制单元、GSM板卡和笔记本电脑组成。利用此系统可以实现 GSM 基站接收机静态灵敏度准确度≤±3 dB、测试距离≤1000 m(视距，LOS)、测试时间≤10 s等，同时该系统支持2个以上 GSM模块或者具有自环回的单个 GSM模块的灵敏度测试。%The project has realized the design of portable BS(Base Station) Test System(BSTS) with GSM900/DCS1800 dual-frequency for the base station sensitivity testing to mobile communication system operation maintenance. The BSTS is composed of the GSM card, signal processing and control unit and notebook computer. The static sensitivity test accuracy of the GSM base station receiver is ≤±3 dB, test distance is ≤1 000 m (Line Of Sight,LOS), test time is ≤10 s. It supports two or more GSM modules or a single GSM module with self-loop back sensitivity test.
