Multicarrier Entropy-Power Loading Enabled the Capacity-Approaching for Optical Wireless Channel
We propose water-filling (WF) strategy based multicarrier entropy-power loading technique to approach the Shannon capacity of optical wireless channel with colored SNR. The normalized gap for the OFDM based VLC system is reduced to 9.31%.
