FIELD: information technology.
SUBSTANCE: method of determining channel quality from a plurality of sub-channels for multi-carrier data transmission comprises steps for providing a sorted noise spectrum containing spectral noise values of the plurality of sub-channels in ascending or descending order, splitting the sorted noise spectrum into fractions with higher or lower spectral noise values, estimating a net background noise power based on the fraction with a lower spectral noise value, determining channel quality based on the estimated net background noise power.
EFFECT: increase in full bit rate or multi-carrier data transmission.
