Abstract
Disclosed is a system and method for transmitting feedback information in a communication system. A receiver calculates a minimum distance of each two symbol vectors among all symbol vectors which can be received through a ksubcarrier among a plurality of subcarriers, in which a channel state of the ksubcarrier and a jprecoder among precoders included in a codebook set are applied; calculates sums of minimum distances by adding minimum distances calculated for the plurality of subcarriers according to each precoder; determines a precoder corresponding to a value greatest among the sums of minimum distances calculated according to the precoders, as a precoder representing the plurality of subcarriers; and feeds the feedback information including a precoder index of the determined precoder back to a transmitter.
