PROBLEM TO BE SOLVED: To provide train radio communication equipment capable of ensuring a good communication state both in an electric field area with high city noise and a low electric field area such as a mountainous area.SOLUTION: The train radio communication equipment prestores correspondence between positional information of a train associated with an electric field intensity of an electric wave of a single frequency from a radio base station device (7) and a noise squelch set value for a noise squelch change circuit 3 included in a receiver, and changes the noise squelch set value according to the positional information of the train from positional information generation units (5, 5a, 5b).SELECTED DRAWING: Figure 1
【課題】都市雑音が高い強電界エリアや、山間部等の弱電界エリアのいずれのエリアにおいても、良好な通信状態を確保できる列車無線通信装置を提供する。【解決手段】無線基地局装置(7)からの単一周波数の電波の電界強度に対応させた列車の位置情報と、受信部に含まれるノイズスケルチ変更回路3に対するノイズスケルチ設定値との対応関係を予め記憶しておき、位置情報発生部(5,5a、5b)からの列車の位置情報に対応してノイズスケルチ設定値を変更する。【選択図】図1
