Abstract: A digital subscriber line transmission system using QAM modulation on several equally spaced discrete tones, uses, at a high transmission rate, N = 2048/p or 4096/p tones spaced by 4.3125p KHz, where p is a power of 2.

Abstract: The present invention relates to a method for setup of a signal in multicarrier modulation, including clipping the signal, in amplitude, with respect to a threshold value, and of reinjecting, with a delay and on the signal to be set up, a clipping noise redistributed, at least partly, outside the useful slip of the signal in multicarrier modulation.
