为了完善基于LED阵列的可见光并行通信系统，探索与之相配的信号调制方案，进行了实验并得出了相关结论。结合可见光并行通信系统的特点以及快速响应(QR)二维码的特征，采用QR码作为可见光并行通信的信息发送方式，研究了基于二维码的动态可见光并行通信系统的调制方案和译码图像处理技术。实验结果表明，该系统能动态发射QR码图像，便于接收，经过一定的图像处理，能正确译码。

In order to make the visible light parallel communication system that is based upon LED arrays more perfect, and explore a suitable modulation technology, some experiments have been conducted and some conclusions are gotten. According to the feature of the visible light parallel communication system and quick response two dimensional (QR 2D) bar code, QR code is used as the information transmit mode of the visible light parallel communication system, and then the modulation scheme of the visible light parallel communication system is studied that is based upon 2D-bar code and the decoded techniques of QR code which is transmitted from the LED arrays. The experimental results demonstrate that QR code images can be transmitted dynamically, received expediently and decoded exactly by the way of the image processing.
