Accurate high-speed propagation prediction method based on measurement [urban microcellular radio]

A new propagation prediction method, aimed at urban microcellular radio systems, is presented. Using the proposed method, the prediction area is divided into some sub-zones to distinguish the changes of propagation environment in it at first. Then, an adaptive coefficient algorithm, based on measurement data, is employed to derive the propagation characteristics of each sub-zone. Finally, we can obtain the field strength distribution of each sub-zone and the 2D coverage of the entire prediction area. Results indicate that the proposed method combines the speed of classic statistical models and the accuracy of classic deterministic models and has good propagation prediction performance for microcellular radio communication systems.
