We experimentally demonstrated full-duplex light-emitting diode (LED)-to-LED visible light communication (VLC) using LEDs as the transmitter and receiver. Firstly, we investigated the performance dependency on the wavelengths of the LED transmitter and receiver by measuring the rise time and signal-to-noise ratio (SNR). Through the investigation, we were able to choose the optimal LED color set for LED-to-LED VLC using Shannon’s channel capacity law. The bit error rate (BER) results of full-duplex and half-duplex LED-to-LED VLC systems with the optimal LED sets are shown to compare the performance. Furthermore, we discuss major distortions and signal losses in the full-duplex LED-to-LED VLC system.

全双工LED到LED可见光通信系统

我们通过实验证明了使用LED作为发送器和接收器的全双工发光二极管（LED）到LED可见光通信（VLC）。首先，我们通过测量上升时间和信噪比（SNR），研究了性能对LED发射器和接收器波长的依赖性。通过调查，我们能够使用Shannon的通道容量定律为LED到LED VLC选择最佳的LED颜色集。显示了具有最佳LED设置的全双工和半双工LED到LED VLC系统的误码率（BER）结果，以比较性能。此外，我们讨论了全双工LED至LED VLC系统中的主要失真和信号损耗。
