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.

摘要： An apparatus and method for cell acquisition and downlink synchronization acquisition in an OFDMA wireless communication system are provided. In an SS apparatus in a broadband wireless communication system, a preamble subcarrier acquirer extracts subcarrier values having a preamble code from an FFT signal. A multiplier code-demodulates the subcarrier values by multiplying the subcarrier values by a preamble code. A correlator calculates a plurality of differential correlations in the code-demodulated signal. An IFFT processor IFFT-processes the differential correlations by mapping the differential correlations to subcarriers. A maximum value detector detects a maximum value from the IFFT signal and calculates a timing offset using an IFFT output index having the maximum value.
