Abstract
It is possible to surely improve the throughput in a handover area in the MIMO communication and increase the cell coverage. Channel estimation units (--) perform a channel estimation by using a common pilot signal transmitted from each base station device and acquire a channel matrix for each cell. Singular value decomposition processing units (--) perform singular value decomposition processing by using a channel matrix corresponding to each cell. Channel capacity calculation units (--) compare a singular value for each path to a threshold value and calculate the number of singular values above a predetermined threshold value as the channel capacity. A cell selection unit () compares the channel capacity sizes and selects a base station device corresponding to a greater channel capacity.
