Modeling and experimental verification of space-time multipath wireless channel based on ray tracing

Aiming at the problems of deterministic modeling, such as limited scenes, large environmental impact, insufficient prediction accuracy, etc.. First of all, this paper has carried out related theoretical research on ray tracing technology, expounding its research status, theoretical basis and method content, algorithm model, etc.. This paper constructs an indoor channel model based on ray tracing, and obtains channel characteristic parameters through accurate simulation analysis of indoor scene buildings. This model can accurately analyze the propagation of indoor wireless signals and guarantees accuracy and accuracy. In addition, this article also built a channel measurement system, using the system to measure and analyze the channel parameter characteristics in the same scene to verify the accuracy of the channel model based on the ray tracing method.
