An Acceleration Algorithm for Collision Detection in Ray- Tracing Propagation

Nowadays, deterministic channel modeling methods play an increasingly important role in the research of wireless communication. With the growing precision requirements in the modeling process, the exploration of increase in computational speed and reduce in complexity is motivated. The improved vector algorithm in ray-tracing simulation presented in this paper realizes the research of the improvement and acceleration of collision detection in three-dimensional (3D) scenarios. Moreover, these methods will guide the construction of fast collision detection algorithm in ray-tracing propagation simulation.
