Patent ID: 8842701

Claim:
A method, comprising: receiving one or more signals at one or more antennas of a receiver; processing the one or more received signals by: decimation filtering the one or more received signals to provide one or more decimated signals each of which having a predetermined symbol size, and enumerating correlation of the one or more decimated signals with a plurality of reference signals to provide correlation results, the correlation results comprising a plurality of correlation output signals each of which corresponding to a respective one of the plurality of reference signals; and detecting a primary synchronization signal (PSS) based on the correlation results, wherein detecting the PSS comprises: searching a radio frame of each of the correlation output signals for a peak signal level to identify one or more candidate signal peaks; searching for an accompanying signal peak at or within one half radio frame of each peak signal level to identify one or more candidate accompanying signal peaks; and determining one of the plurality of reference signals as the PSS based at least in part on the one or more candidate signal peaks and the one or more candidate accompanying signal peaks.
