1. A method, comprising: receiving first and second synchronization sequences that jointly indicate an identity of at least one base station; selecting multiple hypotheses, each hypothesis associating a respective first candidate sequence with the first synchronization sequence and a respective second candidate sequence with the second synchronization sequence; assigning each hypothesis a respective composite score depending on a respective first quality of match between the first candidate sequence in the hypothesis and the first synchronization sequence, on a respective second quality of match between the second candidate sequence in the hypothesis and the second synchronization sequence, and on a similarity between the respective first and second qualities of match, wherein assigning the composite score to a selected hypothesis comprises assigning first and second scores indicative respectively of the first and second qualities of match, calculating a sum of the first and second scores, and correcting the sum based on the similarity; and identifying the at least one base station based on the respective composite scores of the hypotheses.
