10. Apparatus, comprising: a receiver, which is configured to receive a signal carrying first and second synchronization sequences that jointly indicate an identity of at least one base station; and a processor, which is configured to select 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, to assign 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, and to identify the at least one base station based on the respective composite scores of the hypotheses, wherein the processor is configured to assign the composite score to a selected hypothesis by 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.
