The present invention relates to a method and system for communication in a mobile device. First and second OFDM symbols containing first and second received cell-specific reference subcarriers, respectively, are received. First and second received cell-specific reference subcarriers of the first and second OFDM symbols are extracted. A pair of received subcarriers is generated by computing the scalar product of the first received cell-specific reference subcarrier and the conjugate of the second received cell-specific reference subcarrier. A reference sequence is provided, that contains pairs of reference subcarriers for multiple, possible combinations of cell-IDs. The pair of received subcarriers is correlated with each pair of reference subcarriers of the reference sequence to generate cell-specific correlation values associated with each cell-ID of a plurality of cell-specific correlation values. The cell-ID of the strongest cell is determined by searching for the highest correlation value. |
