    摘要: An apparatus and a method for estimating a Carrier to Interference and Noise Ratio (CINR) of an uplink channel in a wireless communication system are provided. The apparatus includes a subcarrier separator for separating subcarrier bundles from a received signal, a detector for calculating squares of correlation values acquired by correlating one or more codewords with signal streams of the separated subcarrier bundles, and a CINR estimator for estimating a CINR using a maximum value and an average value of the correlation value squares calculated at the detector. With the accurate CINR estimated, the channel information delivery and the stable system operation can be achieved.

    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.
