| 1. A method for decreasing an impact of aggregate side lobes of one or more discrete frequency tones in the vicinity of one
or more victim tones, the method comprising the steps of:
calculating an aggregate power of one or more side lobes of one or more disturber tones within a victim bandwidth;
determining at least one optimal load to minimize the aggregate power wherein the at least one optimal load comprises a linear
combination of the one or more disturber tones; and
applying the at least one optimal load to one or more canceller tones for minimizing the impact of the one or more side lobes
of the one or more disturber tones.
