A METHOD TO REDUCE THE PROBABILITY OF CLIPPING IN DMT-BASED TRANSCEIVERS

A new method allowing a reduction in the probability of clipping in di screte multitone (DMT)-based transceivers is described. The method doe s not use any kind of precoding and can easily be implemented within c onventional DMT-transceivers. The main advantage of the proposed metho d is an improvement of system performance in terms of overall signal-t o-noise ratios (SNR's): with the simplest implementation option of the proposed method, up to about 8 dB improvement in the SNR as compared with previously reported brute force clipping methods can be achieved.
