Abstract
A direction deciding unit calculates a plane the perpendicular of which is a directional vector from the wireless communication apparatus toward a radio station. A group deciding unit decides, as groups, antenna combinations each consisting of some ones but not all of a plurality of antennas. A distance calculating unit calculates the distances each between the coordinates of antennas projected, in parallel with the directional vector, onto the plane, and further calculates, for each group, as a group shortest-distance of the group, the shortest one of the calculation results of the distances each between the coordinates of the antennas constituting the group. An identifying unit identifies a group the group shortest-distance of which is the longest. A plurality of communication units communicate with the radio station by use of respective ones of a plurality of antennas in the group identified by the identifying unit.
