Abstract

A method for estimating frequency offsets is disclosed. The method includes shifting a target signal from a first specific frequency band to a second specific frequency band to generate a pre-offset signal according to a frequency shifting direction, performing a specific filtering operation upon the pre-offset signal to generate a filtered pre-offset signal, shifting the filtered pre-offset signal from the second specific frequency band to a base band to generate a base-band (BB) signal according to the frequency shifting direction, and performing a frequency offset estimation upon the base-band signal. The target signal complies with a specific TV format. The specific TV format is an advanced television system committee (ASTC) format or a digital multimedia broadcast-terrestrial/handheld (DMB-T/H) format.
