Abstract
Techniques for pilot-aided carrier frequency and phase synchronization may use a three-pass process. In a first pass, initial frequency offset may be addressed, and a frame start time may be established. In a second pass, a fine frequency correction may be performed. In a third pass, phase variation may be tracked and corrected using a minimum set of pilot symbols.
