Improved Base Band Domain FSO-OFDM Model

As the OFDM can resist the effect of light scatter and it is the principal broadband highspeed transmission technology,it is inevitable to integrate the OFDM and FSO.A modified FSO-OFDM model is proposed to combat the traditional FSO-OFDM model.The modified model can simplify the optical upconvertor and optical downconvertor module byr coding the signal.The simulation results indicate the modified model has the same capability on resisting scatter with traditional model.
