Abstract:
Provided is a base station including a plurality of branches that perform CoMP transmission with another base station, a multiplying unit that multiplies a transmission signal from each of the plurality of branches by a calibration coefficient of each of the plurality of branches, wherein the calibration coefficient is a coefficient obtained by adjusting an individual calibration coefficient acquired by branch calibration between the plurality of branches in the base station based on a branch calibration result between a branch of the base station and a branch of the other base station.
