Due to the bandwidth limitation of the ultraviolet-C[UV-C]optical communication system and strong channel attenuation,it is difficult to transmit high-frequency signals.In this paper,the temporal ghost imaging[TGI]algorithm was first applied to the UV-C communication experimentally,and we realized the transmission of a 4 GHz signal through 95.34 MlHz system bandwidth.The study indicates that the TGI algorithm can significantly improve the signal-to-noise ratio[SNR]compared with the on-off keying method.Our research provides a new approach for alleviating transmission frequency limitation due to poor SNR and insufficient hardware bandwidth.
