Abstract

Systems and methods for quickly acquiring a PSS of a broadcast signal are provided. Such systems and methods include performing a time domain differential correlation on sections of the broadcast signal and identifying peak values in a summation of results of the time domain differential correlation. The systems and method also include performing frequency domain differential correlations between the frequency domain versions of the first section and the second section and identifying ones of maximum values of a ratio of output of the frequency domain differential correlations. Finally, the provided systems and methods include searching for the PSS in localized regions of the broadcast signal that are defined in the time domain by the preconfigured number of peak values and in the frequency domain by the ones of the maximum values of the ratio.
