A wireless transmitter includes: a plurality of transmission antennas; a phase rotating unit which adds phase rotation to signals which are respectively input to the plurality of transmission antennas, and a reception unit which receives information on phase control of arbitrary antennas among the plurality of transmission antennas from another party of communication, wherein the phase rotating units adds first phase rotation for controlling the maximum delay time between the plurality of transmission antennas and second phase rotation for controlling the phases of the arbitrary antennas among the plurality of transmission antennas based on the information. |
