In the atmospheric turbulence, the effects of atmospheric turbulence and transmitted optical power on the BER performance of ultraviolet communication system are analyzed and simulated. The simulation results show that when the atmospheric turbulence strength changes from weak to strong, the BER performance deteriorates along. Compared to OOK intensity modulation, the BPSK subcarrier intensity modulation can be more effectively to inhibit atmospheric turbulence effect on ultraviolet communication system. Under the certain atmospheric turbulence strength, the BER performance of ultraviolet communication system will be improved along with the increase of the transmitted optical power.

Ultraviolet Communication

Based on the analysis of ultraviolet single scattering channel model, the attenuation model of fog and its impact on signal attenuation is investigated. Under foggy environment, the study on the performance of ultraviolet communications is carried, simulation results show that the fog will not only make ultraviolet communication system BER performance deterioration, but also make information transmission rate substantially lowered. In addition, to guarantee a certain system performance indicators, the average transmitted optical power will have higher requirements.

Ber Performance

In the ultraviolet communication system, optical signals being transmitted are not only attenuated in energy, but also affected by the atmospheric turbulence. The effects of atmospheric turbulence intensity and information transmission rate on the BER performance of UV communication system are analyzed and simulated in this paper. It can be found that when the atmospheric turbulence intensity changes from weak to strong, the BER performance deteriorates along, and under the certain atmospheric turbulence intensity, information transmission rate will also have an impact on the system BER performance, the information transmission rate becomes faster, the BER performance gets worse.
