摘要：
Systems and methods are provided for processing Time Domain Multiplexing (TDM) symbols via delayed correlation in the time domain. In one embodiment, a method is provided for determining synchronization information in an Orthogonal Frequency Division Multiplexing (OFDM) broadcast. The method includes employing a time domain correlation to detect the start of an OFDM super frame and utilizing the time domain correlation to synchronize a receiver to the carrier frequency of the OFDM signal.
