摘要：

In this paper,we propose and experimentally demonstrate a bi-directional indoor communication system based on visible light RGB-LED.Spectrally efficient modulation formats（QAM-OFDM）,advanced digital signal processing,pre- and postequalization are adopted to compensate the severe frequency response of indoor channel.In this system,we utilize red-green-blue Light emitting diodes（LEDs）,of which each color can be used to carry different signals.For downlink,the low frequencies of each color are used while for uplink,the high frequencies are used.The overall data rate of downlink and uplink are 1.15-Gb/s and 300-Mb/s.The bit error ratios（BERs） for all channels after0.7 m indoor delivery are below pre-forwarderror-correction（pre-FEC） threshold of3.8×l0-3 To the best of our knowledge,this is the highest data rate in bi-directional visible light communication system.
