摘要
为了简化无线通信信道规划过程,应用几何光学的直线传播原理,建立了传输信号的直射、反射、绕射以及二次反射/绕射的射线跟踪路径模型,在城市区域中构造出二维障碍物群,分析了单个发射/接收天线以及垂直交叉放置的天线组产生的射线路径数,通过对路径寻找方法的分析和数值仿真,给出在一定约束条件下信号传输的有效路径与天线组位置的关系。
In order to simplify procedure of wireless communication channel planning, ray-tracing path models of direct radiation, reflection, diffraction and their second orders＂ paths have been set up. Direct -line transmitting principle of the Geometry Optics is used. Building blocks grope model are constructed in two-dimensional in city. Ray-tracing path number is analyzed between the transmitting and receiving antenna, as well as those antennas with perpendicular cross. With simu- lating and analyzing ray-tracing paths, the relationship between effective paths of signal transmitting and location of anten- nas has been given under some restrictive condition. Result is very useful for the design of wireless channel and antenna function.
