Description

ABSTRACT:
A bit loading for a channel of a multi-carrier data communication system is generated. The bit loading has a target bit rate and satisfies predetermined performance criteria. When the channel is loaded according to the bit loading, a minimal number of sub-channels of the channel are active.
