| Abstract: | This paper gives extensive study and discussion on the transmission problems of wireless signals in an OFDM-ROF optical wireless transmission system through the system simulation. This system is built with the combination of OFDM and ROF technologies and is taken for next generation mobile communications in the near future. Some study results are presented,including the realization of the OFDM-ROF simulation system and several transmission problems of OFDM wireless signals, which are affected by the characteristics of the optical fiber channel with respect of the chromatic dispersion (CD), polarization mode dispersion (PMD) and nonlinearity of the fiber. The numerical analyses are carried out for investigating the system performances damaged by these influence factors through the simulation. |
| Keywords: | 4G OFDM ROF CD PMD nonlinearity effect |
