LEDs (light emitting diodes) can be applied in both illumination and communication. A system of maritime wireless communication with ships based on LED beacons is proposed in this paper. The communication space model and optical transmission model were set up, visible wireless communication manner was analyzed. An anti-fading method combining space and time diversity is adopted due to quick signal attenuation and large noise from nature light interference. After filtering and judgment, the received diversity signals are separated to do bit comparison using Hamming Perception Network. Through analysis and simulation, compared to ordinary space diversity or time diversity way, this kind of anti-fading method can increase reliable communication distance greatly, reduce equipment cost and improve bandwidth utilization rate.
