Abstract

The invention discloses a detection method and device for cell group numbers of secondary synchronization sequences of an LTE (long term evolution) system. The method comprises the following steps of: receiving one group of first correlated sequences and eight groups of second correlated sequences; acquiring corresponding thresholds of the correlated sequences; respectively carrying out peak value processing on the first correlated sequences and second correlated sequences according to the thresholds, setting the values, smaller than the thresholds, of the correlated sequences to be zero, and reserving the values, not smaller than the thresholds, of correlated sequences; when the processed first correlated sequences and second correlated sequences have non-zero values, respectively seeking the maximum correlated values in the first correlated sequences and second correlated sequences and the corresponding index values; and calculating according to the index values to obtain the cell group numbers. The detection method and device disclosed by the invention have the advantages that: a process for peak value processing by utilizing the thresholds is added to the traditional detection method, thus the correlated value detected when the frequency point is wrong is filtered out, the condition of error detection when the correlated value obtained by detecting the wrong frequency point is correspondingly used as the detection result is avoided, the error detection rate is reduced and the detection accuracy is improved.
