ABSTRACT:
Embodiments of the invention provide for assigning bits to a discrete multi-tone modulation communications system. In an embodiment, one or more channels in the plurality of channels are assigned a number of bits based on a performance characteristic of that channel. One or more channels in the plurality of channels may also be assigned a gain value based on the performance characteristic of that channel.
