APPARATUS AND METHOD FOR DETECTING HIGH-SPEED FEEDBACK INFORMATION IN BROADBAND WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for efficiently detecting uplink high-speed feedback information using resources of time-frequency axes in an OFDMA broadband wireless communication system.

SOLUTION: An apparatus for detecting feedback information in a broadband wireless communication system is provided. The apparatus includes: a demodulator which calculates the squares of the absolute values of the correlations to a modulated symbol including a pilot from subcarrier bundle of received feedback information; a codeword correlation calculator which calculates the squares of the absolute value of the correlations of the modulated symbol including pilot corresponding to all codewords for the calculated squares of the absolute values of the correlations of the subcarrier bundle; and a detection determiner which determines whether to perform detection on the feedback information by using the maximum of the calculated squares of the absolute values of the correlations of the codewords.
