Abstract

This paper proposed a pre-equalization method for high-power LEDs visible light communication systems(VLC) systems, which broadens the frequency response range of the light source, extending the 3dB bandwidth of the system from 12MHz to 240MHz, and achieving a maximum data transmission rate of 260Mbit/s. Simulation results show that the pre-equalization method proposed in this paper can broaden the 3dB modulation bandwidth of VLC systems, effectively compensate for the attenuation of the light source at high-frequency response, and improve the transmission performance of VLC systems.
