基于无人机的移动通信实验平台设计

Design of Mobile Communication Experimental Platform Based on UAVS

现有移动通信实验系统一般室内部署,无法重现真实无线信道复杂多变的衰落、干扰特性,针对这一问题,提出了一种基于无人机的无线通信实验平台设计方案,借助于无人机的机动性,通过机载模块采集和测量无线信号和信令信息,实现对信道多径、衰落、干扰等复杂时变特性的研究,完成对多普勒频移、多径衰落、越区切换等现象的实验。同时也可为课程设计、工程训练、实习实训等综合性的实践环节提供软硬件环境。该实验系统灵活度高、可扩展性好、部署方便,可以满足跨课程、多层次的实验教学需求。

The deployed experimental systems today could not work on real wireless channels and complex networks, in order to avoid this defect, we proposed a wireless communication experimental platform based on UAVS. It is able to collect or measure wireless signals and complete signaling information via its flexibility and mobility, thus provides the chance to study the muhipath, fading, interference and other complex time-varying characteristics of channels. It can accomplish the Doppler frequency shift, muhipath fading, cross-zone＇s handover experiments. Moreover, it is capable of providing hardware and software environment for curriculum design, engineering training and practical training. The experiment system has the advantages of high flexibility, good expansibility and convenient deployment, and can meet the needs of cross-course and multi-level experiment teaching.
