The characteristic of scattering and three kinds of inter-link interferences of wireless ultraviolet non-line-of-sight (NLOS) communication are studied. The wireless ultraviolet NLOS single scattering communication simulation model based on Monte Carlo method is established. The correctness of the model is verified by the theoretical formula. Using this model the non-coplanar inter-link interference in wireless ultraviolet communication is simulated. The results show that adjusting the receiving elevation and field angle of the working link receiver reasonably can reduce the inter-link interference and improve the performance of communication system.
