Claim Text:
1. A method, comprising: receiving a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); sampling the PSS at a first sampling rate; downsampling the sampled PSS by a decimation factor to reduce a sampling rate of the sampled PSS from the first sampling rate to a second sampling rate; correlating the downsampled PSS with each of a plurality of correlation reference sequences at the second sampling rate to provide a plurality of correlation values; accumulating the plurality of correlation values to determine a plurality of peak correlation magnitudes; determining a maximum peak correlation magnitude from among the plurality of peak correlation magnitudes; determining symbol timing based on a position of the maximum peak correlation magnitude; and performing SSS detection at the first sampling rate utilizing the symbol timing.
