In a radio base station employing a simultaneous same-frequency multiplexing method, such as a spatial multiplexing method, an index that can be used for performing a control to separate, in an appropriate manner, signals received from mobile stations and multiplexed at the same frequency and that is different from the SIR is calculated, and this calculated index is used to perform the control. A reception response vector estimating unit (524) in the radio base station calculates a reception response vector indicative of the propagation path of a signal from a mobile station to the radio base station. A reception DD ratio calculating machine (51) receives, from the reception response vector estimating unit (524), two reception response vectors calculated about two mobile stations, and calculates a reception DD ratio, which is the ratio between the squares of the magnitudes of the reception response vectors and sends it, to a control unit (80). The control unit (80) judges, based on this reception DD ratio, whether or not to perform a transmission power control or the like. When the reception DD ratio is out of a predetermined value range, the control unit (80) executes the transmission power control or the like. |
