Zusammenfassung:To allow a base station side to quickly recognize communication failure due to breakage of a leaky coaxial cable in a wireless communication system in which the leaky coaxial cable is used for communication between a plurality of a base stations and mobile stations.SOLUTION: Control units 11A and 11B cause transmission units 12A and 12B to generate and transmit an A-series signal and a B-series signal based on transmission data, respectively. The A-series signal passes through an LCX50A and an LCX50B as indicated by a dashed arrow A. The B-series signal passes through the LCX50B and the LCX50A as indicated by a dashed arrow B. The B-series signal passes through the LCX50A and then flows to a base station 10A side, and the control unit 11A recognizes that the B-series signal has flowed via the LCX50B and 50A. When the LCX50A is disconnected, the base station 10A side cannot receive the B-series signal. In this case, the base station 10A side can estimate that the LCX50A or LCX50B is disconnected.SELECTED DRAWING: Figure 2 【課題】複数の基地局と移動局との間の通信のために漏洩同軸ケーブルが用いられた無線通信システムにおいて、漏洩同軸ケーブルの破損による通信の障害を基地局側から迅速に認識する。【解決手段】制御部11A、11Bはそれぞれ送信データに基づいてA系列信号、B系列信号を送信部12A、12Bに生成・送信させる。A系列信号は、破線矢印Aで示されるようにLCX50A、LCX50Bを通過する。B系列信号は、点線矢印Bで示されるようにLCX50B、LCX50Aを通過する。B系列信号はLCX50Aを通過してから基地局10A側に流れ、制御部11AはB系列信号がLCX50B、50Aを介して流れたことを認識する。LCX50Aが切断された場合、基地局10A側でB系列信号を受信することができない。この場合には、基地局10A側では、LCX50A又はLCX50Bが切断したと推定することができる。【選択図】図2
