A front-side position estimation unit (1603) estimates, as an estimated front-side position, a position in the front-side direction, which is the position of the source of the interference wave, when detecting that the interference wave that interferes with the communication by the train has occurred during the travel of the train. A feature extraction unit (1604) extracts a feature of a measured received power value, which is a received power value measured by the train during an interference wave generation period in which the interference wave has been generated. A candidate distance extraction unit (1605) extracts, as extracted candidate distances, candidate distances in which the characteristics of the estimated received power value match the characteristics of the measured received power value from learning data indicating a plurality of candidate distances, which are candidates for the distance between the position of the source of generation of the interference wave and the estimated front-side-surface position, and extracts, as extracted candidate distances, candidate distances in which the characteristics of the estimated received power value match the characteristics of the measured received power value. And indicates, for each candidate distance, a characteristic of an estimated received power value measured by the train when the distance between the position of the interference wave generation source and the estimated front side surface position is estimated to be the candidate distance. A generation source position estimation unit (1606) estimates, as the position of the generation source of the interference wave, the position at which the candidate distance is separately extracted from the estimated front side surface position.

    正侧面位置估计部(1603)在检测到在列车的行驶中产生了干扰由列车进行的通信的干扰波的情况下,将位于干扰波的产生源的位置的正侧面方向的位置估计为估计正侧面位置。特征提取部(1604)提取在产生了干扰波的干扰波产生期间由列车计测出的接收功率值即计测接收功率值的特征。候选距离提取部(1605)从学习数据中提取估计接收功率值的特征与计测接收功率值的特征相符的候选距离作为提取候选距离,该学习数据示出干扰波的产生源的位置与估计正侧面位置之间的距离的候选即多个候选距离,并且按照每个候选距离示出估计为在干扰波的产生源的位置与估计正侧面位置之间的距离为该候选距离的情况下列车所计测的估计接收功率值的特征。产生源位置估计部(1606)将从估计正侧面位置分开提取候选距离的位置估计为干扰波的产生源的位置。
