三维（3-D）射线追踪技术已经发展到可以高精度地为固对移动和移动对移动通信提供延迟扩展、多普勒扩展、角扩展、长短期衰落分布函数等信道参数。这些参数在未来移动通信系统的规范阶段是绝对需要的，以便定义空中接口和各种其他相关的系统参数。本文描述了最先进的光线追踪功能。介绍了卡尔斯鲁厄大学开发的三维射线追踪模型。简要讨论了重要的通道特性参数。基于这些参数，分别通过2 GHz和5.2 GHz的宽带非定向和定向测量验证了模型的正确性。因此，所提出的三维光线追踪模型可用于提取未来移动通信系统规格的参数集并优化现有的移动通信系统
Three-dimensional (3-D) ray tracing has advanced to such a degree that it can provide channel parameters like delay spread, Doppler spread, angular spread, and distribution functions of long- and short-term fading with high accuracy for fixed to mobile and mobile to mobile communications. These parameters are absolutely required during the specification phase of future mobile communications systems in order to define the air interface and a variety of other relevant system parameters. This paper describes state-of-the-art ray tracing capabilities. A 3-D ray tracing model developed at the Universitaumlt Karlsruhe is presented. Important characteristic channel parameters are briefly discussed. Based on these parameters the model is verified by wideband nondirectional and directional measurements at 2 and 5.2 GHz, respectively, showing a good agreement. The proposed 3-D ray tracing model can therefore be used in order to extract parameter sets for the specification of future mobile communications systems and to optimize existing ones
