本文基于几何光学(GO)和统一绕射理论(UTD)，提出了一种用于预测室内场景中传播信道参数的光线跟踪技术，它是一种确定的、全三维的技术。采用平面面片模型对环境进行几何描述。利用角度Z缓冲算法大大提高了射线跟踪的速度，并将预测结果与实测值进行了比较，验证了该方法的有效性。
In this paper, a ray-tracing technique to predict the propagation channel parameters in indoor scenarios is presented, It is a deterministic technique, fully three-dimensional, based on geometrical optics (GO) and the uniform theory of diffraction (UTD). A model of plane facets is used for the geometrical description of the environment. The ray tracing is accelerated considerably by using the Angular Z-Buffer algorithm, Some comparisons between predicted results and measurements are presented to validate the method.
