Abstract:
1. An apparatus for determining feedback information detection in a wireless communication system, comprising: a de-allocator for separating each tile from feedback information; and at least one correlator for correlating a plurality of modulation symbols and a pilot symbol of each tile with a plurality of symbols, corresponding to a codeword, and a pilot symbol for each codeword; and a channel decoder for summing squares of absolute values of the correlated symbols and pilot symbol for each codeword and determining a codeword having a maximum sum; wherein the at least one correlator calculates squares of absolute values of the correlated symbols and pilot symbol; wherein the channel decoder comprises a detection decider for deciding whether to perform detection on the feedback information, and wherein the detection decider determines that the feedback information is reliable if a difference between a maximum of the sums and an average of the sums is greater than or equal to a predetermined threshold, and the detection decider determines that the feedback information is not reliable if the difference between the maximum of the sums and the average of the sums is less than the predetermined threshold.
