Abstract

This paper presents a new multicarrier modulation (MCM) technique based on lattices which achieves a peak-to-average power ratio (PAR) as low as 3. The scheme can be viewed as a 'drop in' replacement for the discrete multitone (DMT) modulation of an ADSL modem. Performance is up to 8.5 dB better than standard DMT in amplifier-clipped conditions. Moreover, the new technique has a lower implementation complexity, O(N), compared with DMT which requires O(N log N) operations. Simulation studies confirm that performance of the lattice-MCM is superior even compared to recent techniques for PAR-reduction in DMT.
