Patent ID: 7817759

Claim:
An apparatus of providing carrier synchronization, the apparatus comprising: a synchronization module comprising electronic circuit configured to perform the steps of, receiving a frame transmitted according to a carrier signal, wherein the frame includes one or more segments separated by a plurality of overhead fields, and the overhead fields include a pilot block that is selectively inserted into the frame to aid carrier synchronization of the carrier signal, generating estimated phase values associated with the carrier signal based on the overhead fields, wherein the overhead fields include preambles that are modulated according to different modulation schemes, estimating phase of the carrier signal associated with a random data field within the segment based upon the estimated phase values of the overhead fields and upon past samples of the carrier signal and future samples of the carrier signal, wherein the segment includes information encoded according to Low Density Parity Check (LDPC) coding, and estimating frequency of the carrier signal based upon the overhead fields or the random data field, wherein the estimating steps are performed on the frame on a segment by segment basis.
