Development of a novel hybrid PDM/OFDM technique for FSO system and its performance analysis

A novel design for FSO communication system is presented. The proposed model is designed by hybridizing PDM and OFDM and its performance is analyzed under different atmospheric turbulences. The proposed design exhibits an improved performance because PDM technique not only boost the user capacity but also enhances the spectral efficiency and OFDM modulation reduces the multipath fading occurred during the FSO transmission. The simulated and measured results confirm the benefits of the proposed design. The proposed system can work as a reference for the FSO application even in bad atmospheric perturbances.
