A method including receiving a received signal in time domain and obtaining a cyclic prefix (CP) correlation on the received signal, the CP correlation including spectral components associated with a plurality of possible cyclic prefix lengths; converting the obtained CP correlation to frequency domain; distinguishing spectral components associated with a first cyclic prefix length from spectral components associated with a second cyclic prefix length; calculating a first metric based on the spectral components associated with the first cyclic prefix length, and calculating a second metric based on the spectral components associated with the second cyclic prefix length; setting an order of cyclic prefix lengths based on a comparison of the first metric and the second metric with a threshold, the order including the first cyclic prefix length and the second cyclic prefix length; and completing a synchronization process based on the order of the cyclic prefix lengths.
