场景传播

本文主要对射线跟踪技术在典型室内场景中的电波传播特性预测应用进行了研究。

This paper mainly deals with the ray tracing technique on predicting the characteristics of indoor wave propagation .

不同的覆盖场景下的无线传播特性、用户分布、用户行为、业务量和业务种类等都不同。

In different coverage scenarios , the wireless propagation environments , user distribution , user behaviors , traffic and service types are all different .

在宽带高移动场景下，无线传播环境变得十分复杂，信道会同时经历时间-频率双选择性衰落。

Under the highly mobile broadband communication scenarios , the wireless propagation environment becomes very complex . The channel will experience the time-frequency doubly-selective fading .

高速铁路电波场景有其特殊性，因此不能简单地套用已有模型，建立适合高速铁路特殊场景的电波传播大尺度模型可为高速铁路无线网络规划、频率规划和干扰等研究提供理论依据。

High-speed railway propagation scenario has its particularity , so only applying the existing model simply is not feasible . Suitable large-scale propagation model for the High-speed railway propagation scenario can supply theory basis to the wireless network planning and the research on the interference and frequency allocation .
