Abstract
The non-line-of-sight ultraviolet single-scatter approximation model is often used to study the channel characteristics and system performance due to its simplification and convenience of giving insight into the link. However, the applicability of the approximate model is easily neglected. In order to specify the application limitations, the applicable conditions and scenes of three approximate models for transceiver optical geometries in coplanar geometries are further investigated based on the classical analytical model. The results indicate that the approximate errors of 0–6 dB induced by optical geometries, especially for the transceiver apex angles which have more influences than the transceiver beam angles, cannot be ignored. In addition, the approximate models are applicable for optical geometries \({<}20\,^{\circ }\). Under this limiting condition, the approximate model of cut and complement matches better with the analytical model in comparison with the approximate models of cuboid and frustum.
