摘要

本文提出了一种利用欠采样相移开关键控调制的光学摄像机通信系统，以支持无闪烁可见光通信。该系统通过发光二极管(LED)灯发送三种类型的光符号，这些光符号由摄像机记录下来。通过采用双LED灯，指定映射和分帧方式，数据速率可达到相机帧速率的3倍。实验结果表明，所提出的摄像机通信系统可以在12 m范围内实现150 bps的无差错通信。

Undersampled phase shift ON-OFF keying for camera communication

In this paper, an optical camera communication system utilizing the under-sampled phase shift ON-OFF keying modulation is proposed to support non-flickering visible light communication. This system sends three types of light symbols through light emitting diode (LED) lamps, which are recorded by a camera. By employing a dual LED lamp with a designated mapping and framing method, the data rate can reach up to 3 times of the camera's frame rate. The experiment results show that the proposed camera communication system can achieve 150 bps error-free communications for a range up to 12 m.
