RADIO ENVIRONMENT ESTIMATION DEVICE, RADIO ENVIRONMENT ESTIMATION SYSTEM, RADIO ENVIRONMENT ESTIMATION METHOD, AND RECORDING MEDIUM

摘要

In order to quickly perform estimation processing while suppressing a deterioration in estimation accuracy caused by the impact of an obstacle present in the vicinity of a sensor, an impact-level assessment unit assesses the level of the impact imparted on an observable at another location by an observable detected by a sensor for detecting observables, which represent the features of an electrical signal obtained by receiving a radio wave. In addition, a weighting factor calculation unit calculates a sensor weighting factor on the basis of the position of the estimation location at which the observable is to be estimated, the position of the sensor, and the assessed impact level from the impact-level assessment unit. Furthermore, a weighted averaging unit estimates the observable at the estimation location by calculating a weighted average of the observable detected by the sensor, by using the sensor weighting factor calculated by the weighting factor calculation unit.
