Abstract

PURPOSE:To realize the transmission of data with high quality, by controlling the AGC of a receiver by means of the control using the external AGC voltage in addition to the internal AGC control with which the output obtained from a part of the receiver is detected for its wave and fed back. CONSTITUTION:A transmitting center 2 and a receiving center 3 of a fixed station are controlled in a communication control room 1 of the fixed station. Thus the data transmission of semi-double communication system is performed between the fixed station and mobile stations 4, 5 and 6 each. Then the control signal is transmitted to the center 3 from the room 1 is accordance with the switching action from the end of transmittion at the fixed station to the reception of data at the stations 4, 5 and 6. A receiver 32 at the center 3 controls the gain by the receiving output of the control signal to ensure the correct reception of the answer data from the outset. In the subsequent reception mode, the gain is controlled according to the output of the receiver 32. In such constitution, the receiver is actuated in the good condition to ensure the reception of data with high quality.
