Abstract:
Systems and methods according to the present invention provide channel estimation methods, systems and devices which determine a coarse channel estimate (40) and a fine channel estimate (66). The coarse channel (40) estimate can be determined based on the channel estimation sequence transmitted to the receiver and then used to detect header symbols. The header symbols can be used to calculate additional channel estimates which can then be combined with the coarse channel estimate (40) to determine a fine channel estimate (66).
