Abstract
A reception device for use in a mobile communication system having a mobile station and a radio base station to which transmission diversity for transmitting transmission signals using a plurality of antennas is applied in a downlink to the mobile station, is disclosed. The reception device includes a presumed probability control unit that sets a presumed probability for use in an antenna verification process of estimating a phase of the transmission signals from the plurality of antennas according to information about a channel of signals transmitted in an uplink from the mobile station to the radio base station when a closed loop transmission diversity control is performed by controlling the phase of the transmission signals from the plurality of antennas according to feedback information noticed by the mobile station to transmit the transmission signals.
