Abstract
A quality factor is associated to each carrier within a multicarrier system wherein a loading constant is computed as the quotient of a difference and the number of carriers that have no bits allocated, the difference being the difference of the sum of the bit error rates for carriers that have no bits allocated and the total remaining number of data bits that are not allocated, and allocating a number of bits to a carrier that has no bits allocated, the number of bits being the difference of the quality factor and the loading constant rounded to nearest integer, repeating the allocation until a predetermined fraction of the carriers have bits allocated, and reiterating the above steps until all carriers have bits allocated.
