Abstract
A method for detecting digital video signal parameters detects an integer carrier frequency offset (ICFO), a pilot pattern and a carrier mode of a signal received by an Orthogonal Frequency-Division Multiplexing (OFDM) communication system. The method includes receiving a first OFDM symbol comprising a plurality of first frequency-domain sub-carriers and a second OFDM symbol comprising a plurality of second frequency-domain sub-carriers; generating a plurality of sub-carrier correlation results according to the first frequency-domain sub-carrier and the second frequency-domain sub-carrier; and determining a maximum sub-carrier correlation result from the plurality of sub-carrier correlation results; and outputting an ICFO, a pilot pattern and a carrier mode corresponding to the maximum sub-carrier correlation result.
