In a mobile communication system having a plurality of terminals including a diversity terminal, an adaptive array base station controls a down-link transmitting power waveform for a terminal establishing access such that transmitting power is decreased at a timing when a reception level of a chip antenna is measured and that transmitting power is increased at a timing when a reception level of a whip antenna as a transmission antenna is measured. In the diversity terminal, therefore, the whip antenna is more likely to be selected as a receiving antenna, thereby improving down-link reception performance. |
