    摘要: An apparatus and method for determining feedback information detection in a broadband wireless communication system are provided. In the detection determining apparatus, a demodulator correlates each of tiles carrying received feedback information with an orthogonal vector including a pilot symbol in each possible codeword, each tile being a predetermined number of subcarriers, and calculates the squares of the absolute values of the correlations. A codeword correlation calculator sums the squares of the absolute value of the correlations of the tiles for each possible codeword. A detection decider determines whether to perform detection on the feedback information based on the maximum of the sums.

    摘要: An apparatus and method for detecting a feedback signal in a multi-cell or multi-sector sector BS in a broadband wireless communication system are provided. A demodulator correlates each tile being sets of subcarriers carrying feedback information received from a serving sector/cell with each possible codeword and calculates the squares of the absolute values of the correlations of the tiles for each possible codeword. A first detection decider sums the squares for each possible codeword and determines whether to perform detection on the received feedback information. If it is impossible to detect the feedback information, a second detection decider receives feedback information from a target sector/cell, combines the feedback information received from the serving sector/cell and the target sector/cell, and determines whether to detect the combined feedback information.
