A communication system (50) in which a plurality of base stations (10 (101, 102,...)) perform transmission on the same frequency at the same timing, wherein a control station (40) serving as a base station control device which gives operation instructions to the base stations (10) gathers the frequency offset detected in each base station (10) for received signals from mobile stations (30 (301, 302,...)) and determines, for each base station (10), the amount of phase rotation, which is the amount of rotation when the base station (10) rotates the phase of the transmission signal, such that the frequency offset of each transmission signal after phase rotation by the base stations (10) is the same. |
