摘要
基于当前自由空间可见光通信应用研究热点,开发了一套结构开放的实验教学平台。该平台实现了模拟语音信号实时无失真传输、模拟视频信号实时传输及数字信号传输。平台的开放性使学生能够在可见光通信系统的调制方式、链路模型、通信性能、应用场景等方面进行研究和创新性开发,从而为综合型、研究型、探索型多层次教学提供有力支撑。
Based on the current research hotspot of visible light communication in free space, an open experimental teaching platform is developed. This platform realizes the real-time undistorted transmission of analog speech signal, real-time transmission of analog video signal and digital signal transmission. The openness of the platform enables students to carry out research and innovative development in the aspects of modulation mode, link model, communication performance and application scenario of visible light communication system so as to provide strong support for comprehensive, research-oriented and exploratory multi-level teaching.
