摘要

This paper reports a novel architecture of hybrid multi-mode fiber (MMF) and visible light communication (VLC) system. The cloud VLC Access Point introduces for the first time. The central station transmits 10 Gbits of baseband optical signal generated by using the LED source over 4 km of MMF to the cloud VLC (C-VLC) terminal point at the smart home network. We assume that all optical background noises have been considered in the VLC channel. A 10 Gbits transferred over 25 m free space optical (FSO) channel using white LED source. A forward error correction channel encoding has been used with nonreturn to zero to transmit the data. All optical background noises have been added to the FSO channel such as white light, red, green, flashlight, yellow, ultraviolet, blue and spectrum light sources. The VLC receiving system has an optical filter and maximum likelihood sequence estimation equalizer. The harmonic components are discard using the low pass filter. The simulation results show that the system model has a typical performance with zero bit error rate.
