Transmission characteristics due to multipath dispersion of indoor wireless optical communication

In this paper, transmission characteristics due to multipath dispersion of indoor optical wireless communication has been analyzed through the simulations and the experiments. Results of simulation using channel modeling have shown that one-reflected response h¹ is 63.6 % of the total power and the difference of the magnitude response of DC and 500 MHz is 7 dB. To assess the system performance, eye diagrams of the system have been measured over RF modulation voltage V _pp=7~10 V. Good transmission performance of the system have been shown over V_pp=8.5~10 V. Standard deviation, due to multipath dispersion, of the pulse width of the systems is 22 ns
