Abstract

White LED (light emitting diode) offer advantageous such as high brightness, lower power consuption and long life spand, and is expected to be the next generation of lamp. The other merits of LED are high sensitivity and fine modulation performance. An indoor optical wireless communication system is propsed and three kind of modulation schemes are compared in band requirement and power requirement. Nine LED lights are installed in the different of the room celling, so the RMS (root-mean-square delay spread) delay is also consided in hight bit rate enviroment, the power loss and BER are presented under different time delay. The simulation results show that, the MPPM is bandwidth efficeient than PPM and OOK. At the condition of high bit rate, MPPM performance much better than OOK and PPM with low BER.
