When solar-blind wireless ultraviolet light system is used to communicate, if multiple links are active at once, the active links will overlap with effective scatters in space, resulting in mutual interference and a reduction in communication performance. This study develops a method for simulating the wireless ultraviolet non-line-of-sight communication scattering channel and validates the model's accuracy by comparing it to a common interference model. And this model is used to simulate the co-planar interference, non-co-planar interference, and the link interference model under non-co-planar and height difference interference in wireless ultraviolet communication. The results show that the main factors affecting the bit error rate of the channel are the location of the interference terminal and the size of the effective scatterer, in the case of non-co-planar and height difference interference, the inter-link interference can be reduced by adjusting the transmitter elevation angle, and the performance of the communication system can be improved.
