Abstract
Disclosed are a method and a device for differently applying phase rotations for each antenna by dividing a frequency band in order to solve a problem in which reception performance deteriorates in a specific subcarrier when the correlation between antennas is high. According to the present invention, a method by which a transmitter transmits a signal comprises the steps of: estimating the transmission correlation between respective transmission paths; calculating a phase rotation value to be applied to a transmission signal on the basis of the estimated transmission correlation; applying a phase rotation in accordance with the phase rotation value to the transmission signal; and transmitting the transmission signal.
