根据几何光学和统一绕射理论城市微蜂窝通信中的信号传播模型,使用射线跟踪技术,考虑了跟踪过程中射线在墙面和地面的反射及射线在建筑物拐角处的绕射。对某小区的电波传播特性进行计算,分析不同区域的路径损耗。
According to the signal propagation model of urban microcellular communication based on geometrical optics and unified diffraction theory, the ray tracing technique is used to consider the ray reflection on the wall and the ground and the diffraction of the ray at the corner of the building in the tracking process. The radio propagation characteristics of a cell are calculated, and the path loss in different regions is analyzed.
