Abstract:
A base station (10) according to the present invention includes: a plurality of amplifiers (15a, 15b) configured to amplify radio frequency signals; a plurality of antennas (16a, 16b) configured to transmit the RF signals amplified by the plurality of amplifiers (15a, 15b); a judging unit (123) configured to judge whether or not to transmit the RF signals by applying a transmission diversity using the plurality of antennas (16a, 16b); and a baseband signal processor unit (12) configured to generate baseband signals having an identical symbol pattern and an identical amplitude, as baseband signals that are bases of the RF signals to be transmitted from the plurality of antennas (16a, 16b), when the judging unit (123) determines not to apply the transmission diversity.
