| 摘要 |
The present invention relates to a wireless transmitter comprising 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; a receiving module which receives the information for controlling the phases of arbitrary antennas among a plurality of antennas of the other transmission side, wherein the phase rotating units adds first phase rotation to signals for controlling the maximum delay time between the plurality of transmission antennas and second phase rotation for controlling the phases of arbitrary antennas among the plurality of transmission antennas based on said information. |
