According to one embodiment, a wireless transmission method is disclosed. The method can perform feedback loop processing including subtracting a feedback data signal obtained by multiplying a feedback processing data signal by a gain from an input data signal to generate the feedback processing data signal. The method can perform beam forming processing with respect to the feedback processing data signal and at least one pilot signal for channel estimation to generate a beam-formed signal. In addition, the method can transmit the beam-formed signal by a plurality of antennas. Precoding processing performed on the pilot signal is only beam forming processing.
