Abstract

PURPOSE:To suppress the answer signal caused by the overreach by specifying the output power of the suppressing transmitter to the reception power and by the properties of the modulated wave. CONSTITUTION:During the transmission via ground transmitter/receiver 4, the contact of power switch 5 is opened, and the transmission output of 4 is supplied to, for example, LCX1-2 through leak coaxial cable LCX switch 2 to be transmitted to the mobile station connected to the train line which incorporates LCX. Here switch 2 is connected to LCX incorporating the train line connected to the mobile station which aims 4 as the object of information transmission. While the transmission is given from the mobile station, the contact of switch 5 is closed. And the transmission output of the mobile station is combined to the output of reducing transmitter 6 to be applied to 4. In this way, the mistransmission to the transmitter/ receiver at the ground station can be prevented for the signals sent from the shafts on the lines excepting that which incorporate the corresponding LCX.
