1. A multicarrier communications method, comprising:

  • modulating, in a transceiver, a first plurality of bits onto a first plurality of carriers using a first Signal to Noise Ratio (SNR) margin; and

    modulating, in the transceiver, a second plurality of bits onto a second plurality of carriers using a second SNR margin,wherein the first plurality of carriers is different than the second plurality of carriers,wherein the first SNR margin specifies a first value for an increase in noise associated with the first plurality of subcarriers,wherein the second SNR margin specifies a second value for an increase in noise associated with the second plurality of subcarriers, andwherein the first value for the increase in noise is different than the second value for the increase in noise.
