电磁频谱感知教学实验系统的设计与实现

摘要

This paper designs a general scheme of the electromagnetic spectrum sensing teaching experimental system, builds the hardware platform and realizes all software modules. Test results show that the experimental system can meet the design requirements perfectly. It is simple and reliable, and visualizes the abstract theory of spectrum sensing and other characteristics. So the experimental system is extraordinarily suitable for the practice of teaching experiments, and also suitable as a development platform of electromagnetic spectrum sensing research project.%本文设计了一种电磁频谱感知教学实验系统的总体方案，搭建了硬件平台并实现了各软件模块。测试结果表明，该实验系统完全满足设计要求，具有简单可靠、将抽象的频谱感知理论直观化等特点，非常适合教学实验使用，也可以拓展作为频谱感知研究项目的开发平台。
