In order to improve the system bandwidth and realize high-speed real-time visible light communication, this paper proposed an analog pre-emphasis method based on a red LED, which equalized the high-frequency signal of the red LED in the frequency domain. A field programmable gate array (FPGA) generated non-return-to-zero on-off keying (NRZ-OOK) modulated signal, which was pre-emphasized by an analog pre-emphasis circuit and then emitted by a red LED. The experimental results show that the proposed method achieves a communication rate of 246Mbps and a BER of 0 under the experimental conditions of a communication distance of 3m, LED power of 0.3W, and a real-time communication duration of 1 hour.
