Abstract
A discrete multitone signal has a much higher peak to average ratio than a comparable single tone modulation signal. Therefore a DMT transmitter has to either have a significantly more expensive analog front end (both in terms of the DAC, the analog filter and line driver) or it has to control the amount of clipping. We describe two general techniques for clipping control and present performance comparisons to previous techniques.
