A modulated signal, sent from the base station, for controlling the transmission power is demodulated to reproduce a first data unit representing the class of receive field intensity at the base station and, at the same time, the modulated signal is envelope-detected to generate a second data unit representing the receive field intensity of the modulated signal, the classes corresponding to the first data unit are subdivided according to the second data unit, and a control voltage corresponding to a subclass is generated. The amperage of the source current to the transmission amplifier is controlled with that control voltage, and the transmission power is thereby controlled. <IMAGE> |
