摘要： An apparatus is provided for receiving channel quality information (CQI) in a mobile communication system in which a mobile station feeds back downlink CQI over a CQI transmission channel. In the apparatus, a power correlation estimator correlating code values mapped to tiles, wherein the CQI transmission channel includes a plurality of the tiles distinguished by time and frequency resources. A maximum detector detects CQI corresponding to a code value having the maximum power correlation value among estimated power correlation values. A threshold comparator compares the detected CQI with a CQI threshold, and outputs the detected CQI as final CQI if the detected CQI is greater than or equal to the threshold.
