<p><P>PROBLEM TO BE SOLVED: To solve the problem wherein sufficient communication states may not be obtained depending on assigned slots and positions of radio receivers. <P>SOLUTION: The radio receiver includes a plurality of transmission antennas, and a reception section. The reception section receives signals from a radio transmitter. The radio transmitter transmits data to which first phase rotation for controlling the maximum delay time among the plurality of transmission antennas is added according to whether transmission is performed by frequency diversity, and pilot channels orthogonally crossing among the plurality of transmission antennas. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
