Patent ID: 8130873

Claim:
A carrier recovery apparatus, comprising: a multiplier to receive a vestigial side band (VSB)-modulated signal and to multiply the received VSB-modulate signal with a carrier signal to generate a baseband VSB signal; an upper sideband detecting unit to detect an upper sideband of the baseband VSB signal and to generate upper phase information corresponding to the detected upper sideband; a lower sideband detecting unit to detect a lower sideband of the baseband VSB signal and to generate lower phase information corresponding to the detected lower sideband; a carrier signal adjustment unit to adjust the carrier signal according to the upper and lower phase information and to output the adjusted carrier signal to the multiplier; and a pilot detecting unit to detect a pilot signal of the baseband VSB signal and to generate pilot phase information corresponding to the detected pilot signal, wherein the carrier signal adjustment unit adjusts the carrier signal according to the upper phase information, the lower phase information, and the pilot phase information, wherein the upper phase information and the lower phase information are capable of recovering the carrier signal.
