Abstract
PURPOSE:To attain the control of a transmitting power while an optimum receiving is held by deriving a transmitting output control value added to the time change of a receiving power. CONSTITUTION:At a receiving side R, a receiving signal is outputted from a terminal through a receiving device 8. The intensity of a receiving signal is detected by an electric field detecting device 10, a part of the detecting output is converted to the change of a receiving electric field to the time in a differential circuit 11, given to a coefficient device 13 and the coefficient is properly changed by the range of the receiving electric field. A part of the detecting output is inputted to a coefficient device 12 for a transmitting power. The output of respective coefficient devices 12 and 13 is supplied to integrating circuits 14 and 15, a corresponding control voltage is obtained, respective control voltages are added 16 and sent through a receiving side control circuit 17 to a transmitting side control circuit 18. The circuit 8 controls a variable attenuating control circuit 2 and a transmitting power is controlled.
