Abstract
Disclosed in the present disclosure is a ray tracing channel modeling method for reconfigurable intelligent surface wireless communication. The method comprises: setting an application scene; implementing RIS deployment and adjustment mode; analyzing a received power distribution of a non-line-of-sight scene; analyzing an angle power spectral density; and specifically analyzing the change of a channel capacity with the change of a transmitting power, a RIS unit number and a RIS deployment position. In the present disclosure, a RIS channel deterministic model based on ray tracing can be used for a static ray tracing simulation software, the deployment of any scale of a reconfigurable intelligent surface at any position in a scene is supported, the ray tracing modeling method of the reconfigurable intelligent surface is enriched, and the channel characteristic analysis of the simulation result has guiding significance for the application and deployment of RIS in indoor scenes.
