Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated and it has much wider bandwidth then traditional communication systems. This increased the research done in the field of visible light communications. However a proper indoor channel model is lacking and all previous studies assumes that only additive white Gaussian noise (AWGN) is present. Lack of proper channel model has motivated us to model a realistic indoor visible light channel. After modeling the indoor visible light channel, the performance of an asymmetrically clipped optical OFDM (ACOOFDM) system which is suitable for optical communications is investigated and compared to that of the AWGN optical channels. © 2015 IEEE.trinfo:eu-repo/semantics/closedAccessACOOFDMIndoor channel modelingOFDMVisible light communicationLightOrthogonal frequency division multiplexingRadio communicationVisible light communicationWhite noiseACOOFDMAdditive White Gaussian noiseAsymmetrically clipped Optical OFDMChannel modelCommunication engineersIndoor channel modelOptical channelsPerformance analysisGaussian noise (electronic)Conference Object2102210510.1109/SIU.2015.71302852-s2.0-84939187308
