Paper Abstract

The conventional visible light (VL) communication signals based on the LED array and photodiode severely decreases at the far away receiving point in the VL channel by the path loss effect and the insufficient compensation capability of the receiver, which results in failure of long-range VL communication for smart indoor service. In this paper, we consider the long-range VL communication technique that the compensation extent of the path loss distortion provides in advance by threshold map, and utilizes the optimal transceiver circuit for long-range VL communication. And so we can see that the proposed long-range VL communication technique overcomes the path loss problem through the compensation effect from utilizing the optimal threshold voltages into VL receiver, and attains the success of longrange VL communication test in the overall range from zero to 1070 cm distance.
