A system and method for providing bit-loading enhancement is provided,
including methods of determining an extended bit capacity for a plurality
of carriers, wherein a first portion of the plurality of carriers is
loaded and a second portion of the plurality of carriers is initially
unloaded and bits are allocated between said first and second portions in
accordance with power requirements for loading bits onto said first or
second portion of the plurality of carriers, as well as methods of
optimizing the average signal to noise margin for a plurality of carriers,
wherein a first portion of the plurality of carriers is loaded and a
second portion of the plurality of carriers is initially unloaded, and
bits are loaded from the first portion onto the second portion in
accordance with a power savings related to such a loading from the first
portion onto the second portion.
