| Abstract: | In order to enlarge communication distance of ultraviolet communication system, an ultraviolet laser based communication system is proposed by taking the advantage of photomultiplier tube as optoelectric detector and by taking cyclic redundancy check （CRC） as encoding method, and the conventional FSK modulation is improved. Experiment results are analyzed by setting up experiment platform of ultraviolet laser communication system, the impact of communication distance on error encoding rate is discussed, and finally the ultraviolet laser communication system with transfer rate 0.6kb/s and with less than 10.5 error encoding rate is implemented in the range of 150m communication distance in day time and 220m communication distance at the night. |
