<p><P>PROBLEM TO BE SOLVED: To solve the problem wherein a conventionally proposed communication system cannot fully obtain multi-user diversity effects with an allocated slot at the position of a radio receiver. <P>SOLUTION: The wireless transmitter comprises a plurality of transmission antennas, a phase rotation unit which adds phase rotations to output signals to the plurality of transmission antennas, and a reception unit which receives information regarding phase control over an arbitrary antenna among the plurality of transmission antennas from a communication partner, the phase rotation unit adding a first phase rotation for controlling a maximum delay time of the plurality of transmission antennas and a second phase rotation for controlling the phase of the arbitrary antenna among the plurality of transmission antennas on the basis of the information. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
