PROBLEM TO BE SOLVED: To provide a train radio system in which an estimated transmission line candidate can be surely selected at a reception portion of a train and reception processing is performed with high precision.SOLUTION: A current position detector 31 detects the current position P9 of a train 9 and outputs the current position P9 to an estimated transmission line candidate information update unit 33. The estimated transmission line candidate information update unit 33 determines validity/invalidity of each of film antennas FT1 to FT3 on the basis of the current position P9 of the train 9, removes the reception signal of a film antenna determined as being invalid from preliminary estimated transmission line information, and updates to estimated transmission line candidate information D1 which defines estimated transmission line candidates C1 to CN associated with residual valid reception signals. The estimated transmission line candidate information update unit 33 preserves the estimated transmission line candidate information D1 into the estimated transmission line candidate storage unit 32 independently of the preliminary estimated transmission line candidate information.

    【課題】列車の受信部において推定伝送路候補を正確に選択して精度の良い受信処理が行える列車無線システムを得る。【解決手段】現在位置検出部31は列車9の現在位置P9を検出して推定伝送路候補情報更新部33に出力する。推定伝送路候補情報更新部33は、列車9の現在位置P9に基づき、フィルムアンテナFT1〜FT3それぞれの有効/無効を判断し、推定伝送路候補記憶部32に格納された予備推定伝送路情報から、無効と判断したフィルムアンテナの受信信号を除去して、残存した有効受信信号に関連づけた推定伝送路候補C1〜CNを規定した推定伝送路候補情報D1に更新する。そして、推定伝送路候補情報更新部33は、推定伝送路候補情報D1を、予備推定伝送路候補情報とは独立して推定伝送路候補記憶部32に保存する。【選択図】図2
