Abstract

calculating an input signal of N field without considering a starting point in a field operating unit(410); taking correlations between the data resulting from the operation and a reference signal of a reference signal generator in a ghost cancelling system(420); keeping the orignal phase if the correlation value is positive or performing the phase inversion of the data if the correlation value is negative(430-460); thereby saving the reference signal extracting time.
