Document Type and Number:
WIPO Patent Application WO/2023/012859
Kind Code:
A1
Abstract:
A lateral position estimation unit (1603) estimates, as an estimated lateral position, a position of a source of an interfering wave in a lateral direction, when it is detected that the interfering wave that interferes with communication performed in a train has occurred while the train is traveling. A feature extraction unit (1604) extracts the features of a measured received power value, which is a received power value measured on the train during an interference wave occurring period when the interfering wave occurs. On the basis of training data indicating a plurality of candidate distances, which are candidates for the distance between the position of the source of the interfering wave and an estimated lateral position and showing the features of an estimated received power value estimated to be measured on the train when for each candidate distance, the distance between the position of the source of the interfering wave and the estimated lateral position is the candidate distance, a candidate distance extraction unit (1605) extracts, as an extracted candidate distance, a candidate distance where features of the estimated received power value match features of the measured received power value. A source position estimation unit (1606) estimates, as the position of the source of the interfering wave, a position separated by an extraction candidate distance from the estimated lateral position.
