ABSTRACT:
A radio communication system that uses multiple antennas to transmit signals to a plurality of mobile terminals, and that measures the reception quality of each signal that is transmitted from each antenna on a transmitting side and received by the mobile terminal, determines a main antenna based on that reception quality for real-time communication, calculates multi-dimension correlation between the main antenna and other antennas, selects resources where the multi-dimension correlation is lower than a set value, feeds back data to the transmitting side indicating the main antenna, low correlation resources and reception qualities, designates antennas having resources of low correlation as diversity antennas, and performs diversity transmission from the transmitting side of signals to the mobile station using those diversity antennas and the main antenna.
