Abstract
A system and method utilize a dual correlation, one for the synchronization pattern (sync correlation) and one for the channel equalization pattern (CE correlation), to determine where the channel equalization pattern starts and thus establish frame synchronization. The system and method compare the two correlations and decides on the start of the channel equalization symbols when the CE correlation is larger than the sync correlation.
