1. A wireless device to transmit information for a counterpart wireless device, comprising:

  • a signal processor to generate a symbol sequence;

    a transmission vector calculator to convert the symbol sequence into a plurality of transmission symbol sequences, and control phases of the transmission symbol sequences to be a coordinate phase or an opposite phase based on a channel estimation to the counterpart wireless device;

    a plurality of antennas to respectively transmit the plurality of transmission symbol sequences;

    an uplink receiver to receive an uplink signal from the counterpart wireless device;

    a channel estimating unit to estimate the channel estimation based on the uplink signal; and

    an array gain controller to generate array interferences to the counterpart wireless device based on the channel estimation, and select an array interference having a higher gain of a signal for the counterpart wireless device from among the generated array interferences,wherein the transmission vector calculator controls the phases to be a combination of phases in which the respective phases of the transmission symbol sequences generate the array interference selected by the array gain controlling unit.
