Frame-based carrier frequency and phase recovery system and method

摘要

Header information is used to facilitate coarse frequency and frame recovery. The coarse frequency and frame recovery is thereafter utilized to perform adaptive phase and frequency synchronization on a frame-by-frame basis. In one aspect, a frame identifier in a physical layer header of the digitized signal is utilized to estimate a first phase associated with the frame identifier. The remaining portion of the physical layer header is utilized to estimate a second phase associated with the remaining portion. The first phase estimate and the second phase estimate are combined to generate a first combined phase estimate.
