Abstract

Visible light LEDs are being used for indoor optical wireless communication system as well as the illumination of rooms. The visible light communication system based on LEDs can attain high luminosity as a lighting source, and thus high quality transmission for an optical wireless system. In indoor diffuse optical wireless links multi-path dispersion limits the maximum transmission data rates. The relation between optimal strategies of light source and received optical power has been discussed. The optical diversity reception technology has been given to get rid of intersymbol interference and increase the SNR. And the model of the optical detector's layout is given. The system simulation model is built, and the relation curve between BER and root-mean-square delay spread of OOK-NRZ and OOK-RZ is given.
