Positioning model for urban microcell based on 3D ray-tracing method
基于三维射线跟踪方法的城市微小区定位模型*

This paper presented a positioning model based on ray-tracing method.According to calculate the unique electromagnetism characteristic in the complex environment of urban microcell by using 3D ray-tracing method,this model could generate a positioning database.The users' location estimates could be achieved by comparing the electromagnetism characteristic parameters recorded at location point with the positioning database generated by the computer.Simulation result shows that the model is effective and can ...
