Abstract(in English) | A path loss model is a fundamental method to roughly predict radio propagation characteristics. However, most conventional models do not consider the anisotropy of radio propagation. If geographical conditions, such as the number of buildings, are irregularly change, the radio propagation characteristics may significantly fluctuate. This paper proposes the partitioned path loss models based on coefficient of determination. The proposed method first collects the instantaneous received signal power via a measurement campaign and these datasets are transformed to the polar coordinate. Thus, a path loss model is estimated in each azimuth region and several path loss models are unified using coefficient of determination. Through the emulation results using measured datasets in the cellular communication, we can confirm that the proposed method accurately estimates the radio propagation compared to the single path loss model. |
