1. A method for processing a multiple carrier signal provided with subcarriers distributed in a band, comprising:
calculating a subcarrier noise of an edge of the band;
calculating a subcarrier noise of a center of the band;
calculating a first ratio of the subcarrier noise of the edge of the band to the subcarrier noise of the center of the band;
determining whether the first ratio is greater than a threshold;
acknowledging that the edge of the band suffers from interference when the first ratio is greater than the threshold; and
dividing the first ratio by a ratio of a frequency width of the edge of the band to a frequency width of the center of the band.
