Abstract
A synchronization signal includes a plurality of predetermined synchronization symbols shaped by a predetermined symbol pulse. A receiver ( ) receives ( ) a signal including the synchronization signal, and a processor ( )determines ( ) a first plurality of cross-correlations between the predetermined symbol pulse and the received signal. The processor calculates ( ) a plurality of sums of products of the plurality of predetermined synchronization symbols and a predetermined subset of the first plurality of cross-correlations. The plurality of sums are mathematically equivalent to a second plurality of cross-correlations between the synchronization signal and the received signal. The processor locates ( ) a peak of the plurality of sums to establish receiver synchronization.
