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.
