Abstract
A method of transmitting/receiving feedback information representing channel quality in a MIMO-OFDM system, in which a receiver measures channel qualities of signals transmitted on a plurality of subbands through a plurality of transmitting antennas by a transmitter, selects a predetermined number of subbands having a highest transmission performance based on the measured channel qualities and preceding information, determines at least one subband group with a maximum rate from among the selected subbands and the preceding information associated with the at least one subband group, and transmits feedback information to the transmitter, the feedback information including channel quality information about the at least one subband group and the associated preceding information.
