Apparatus and method for pilot-less carrier acquisition of vestigial sideband (VSB) signal

摘要

A method for demodulating a carrier wave in a channel environment in which a pilot signal may be distorted, in a digital TV receiver, which may receive a vestigial sideband (VSB) modulated and transmitted signal, and a demodulation apparatus therefor are provided. A field synchronization part of a VSB signal, in which a pilot signal may be removed, may be used as a reference signal for synchronization. The frequency offset of a carrier wave may be estimated through self-correlation of a signal, and the phase offset of the carrier wave may be estimated through a pilot-less frequency and phase locked loop (FPLL).
