Abstract: “The foremost challenge that FSO come across is the transmitting media linking transmitters and receivers where many weather conditions can influence the capacity of the FSO link such as level of rain, haze, Fog, cloud bursting, scattering and turbulence resulting in fading of the transmitted signal and causing high bit error rate or signal loss at the receiver end. In this work, the impact of turbulence on OFDM-OTSB-FSO system is modeled and analyzed using the gamma-gamma distribution modeling at 10 Gbps over the FSO link. To achieve high speed FSO link under the sway of small and high scale turbulence variations, OFDM-OTSB treated data transmission is reported and demonstrated.”
