| Abstract: | Recently,with the progress of ray-tracing,precise prediction in radio propagation comes true by the implement of accurate 3D map.But the method involues problems to solve.Taking the reality of the present city 3D map and controllable cost into account,a new method of radio propagation prediction was proposed and implemented based on the combination of ray-tracing and conventional method in radio propagation prediction as well as computer aid analysis.Interrelated analysis was also shown. |
