We propose a vsible light communication scheme utilizing red, green and blue light-emitting diodes (LEDs) and three color-tuned photodiodes. Amplitude shift keying modulation is considered, and its effect on light emission in terms of flickering, dimming, and color rendering is discussed. The presence of interference at each photodiode generated by the other two colors is used to improve detection since interference is symbol-dependent. Moreover, the capability of the photodiodes to follow the LEDs speed is considered by analyzing the possibility of equalizing the received signal, and also self-interference mitigation is proposed. The system performance is evaluated both with computer simulations and tests on an Arduino board implementation.
我们提出了一种利用红色、绿色和蓝色发光二极管（LED）以及三个颜色调谐光电二极管的可见光通信方案。考虑了幅移键控调制，并讨论了其在闪烁、调光和显色方面对光发射的影响。由于干扰与符号相关，因此利用其他两种颜色在每个光电二极管处产生的干扰来改善检测。此外，通过分析均衡接收信号的可能性来考虑光电二极管跟随LED速度的能力，并提出了自干扰缓解措施。通过计算机模拟和在Arduino板实现上的测试对系统性能进行了评估。
