摘要：A reception quality information obtaining unit obtains reception quality information indicating reception quality of each of a plurality of antennas at predetermined intervals. A reception quality variation trend recognition unit recognizes a variation trend of a value in relation to reception quality of each of the antennas obtained. A correlation determination unit determines a degree of correlation between the antennas based on the variation trend of the value in relation to the reception quality of each of the antennas recognized. An antenna selection unit selects at least two antennas to be used for wireless communication, based on the degree of correlation between the antennas determined by the correlation determination unit.

主权项：1. A wireless base station having a plurality of antennas and performing wireless communication by using at least two antennas comprising: an obtaining unit that obtains information concerning reception quality of each of the plurality of antennas; a recognition unit that recognizes a variation trend of a value in relation to reception quality of each of the antennas obtained by the obtaining unit; a determination unit that determines a degree of correlation between the antennas based on the variation trend of the value in relation to the reception quality of each of the antennas recognized by the recognition unit, and a selection unit that selects at least two antennas, among the plurality of antennas, to be used for wireless communication, based on the degree of correlation between the antennas determined by the determination unit.
