SIGNAL TO NOISE RATIO MARGIN EQUALIZATION IN SYSTEMS WITH CODED MODULATION
A method that accomplishes margin equalization utilizing tone ordering is provided. The method includes measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel. A plurality of tone groups is determined by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group. Ordering information describing the plurality of tone groups is communicated to a transmitter. The transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.
