摘要：

随着固态光源的发展，大功率LED已被广泛应用到照明中。将照明功能与通信功能结合的室内可见光通信系统将有广泛的应用前景。为了满足室内照明和通信要求，通过使用大功率LED构成阵列，设计发射端、接收端，接口模块，构建了基于强度调制及直接检测方法的全双工可见光通信系统。并对系统信道模型进行分析，对单向链路实际光强分布及其可靠通信范围进行实际测量。实验证明该系统的可行性和可靠性。

Abstract:

With the development of the solid state light source, the high power LED has been widely applied in the illumination. The indoor visible light communication system has broad application combining the illumination and the communication. In order to meet the requirement of indoor illumination and communication, a full duplex communication system is structured by designing the transmitter, receiver and interface module based on the intensity modulation and direct detection modulation. The channel model is analyzed. The actual intensity distribution and the reliable communication distance of the one-way link are measured. The experiment proves the feasibility and the reliability of the system.

Key words: optical communication, visible light communication system, illumination, line-of-sight channel, full duplex communication
