An interference detector receives a data stream including predetermined symbols that include a first data and a second data, between which is a frequency offset. The interference detector includes a correlation apparatus that generates a first correlation result and a second correlation result according to the data stream; a power searching unit, coupled to the correlation apparatus, that generates a first maximum correlation result and a first neighboring power according to the first correlation result, and generates a second maximum correlation result and a second neighboring power according to the second correlation result; and a determining unit, coupled to the power searching unit, that generates a determination result according to the first maximum correlation result, the first neighboring power, the second maximum correlation result and the second neighboring power to indicate existence of interferences.
An interference detector for processing a data stream having a predetermined symbol comprising a first data and a second data, with a frequency offset between the first data and the second data, the interference detector comprising:
A method for detecting interferences, applied to a receiving end of a digital television (TV) for receiving a data stream having a predetermined symbol comprising a first data and a second data with a frequency offset between the first and second data, the method comprising:
