一种小微站高保真模拟测试系统的设计与实现

Designing and Implementation of a High-Fidelity Simulation and Test System for Femtocell

针对TD-LTE移动通信系统的大规模建设和优化需要,中国移动设计院创新研发、批量生产并规模应用了一种基于商用终端芯片的高保真模拟测试系统,可模拟小微基站发送高保真的真实导频信号,解决了模测工作中信号的高保真及设备的便携性问题。该方案同样适用于FDD制式通信系统以及未来5G系统的小微基站场景。

According to the requirements of TD-LTE mobile communication systems for large-scale construction and optimization, a high-fidelity simulation and test system based on commercial chip was developed innovatively and produced in batch and applied widely, which can simulate the high-fidelity pilot signal sent by femtocell and solve the high-fidelity signal in the simulation task and the equipment portability. The system is also suitable for the FDD communication system and the future 5 G femtocell scenario.
