ABSTRACT:
A reception apparatus capable of preventing saturation and sensitivity degradation of a receiver when base transceiver station transmit power control is performed and calibrating offset voltage without increasing the amount of current consumption. In this apparatus, a gain setting section (109) estimates reception field intensity of each time slot in the next frame based on information of the reception field intensity and transmit power information which is information of the transmit power of the base transceiver station and calculates a gain set value according to the estimated reception field intensity. A gain control circuit (110) extracts a maximum gain out of the gains set by the gain setting section (109), uses the maximum gain as a set gain for DC offset voltage calibration and performs gain control at the gain set value corresponding to each time slot. A voltage calibration circuit (111) performs the DC offset voltage calibration of the received signal.
