Abstract

Orthogonal frequency division multiplexing (OFDM) and in particular discrete multitone (DMT) modulation has been proposed for the physical layer of wideband wireless local area networks. As an alternative, filtered multitone (FMT) modulation can be also considered, since it exhibits significantly lower spectral overlapping between adjacent subchannels, so providing higher transmission efficiency than DMT. In this contribution, we investigate the possible advantages of FMT over DMT modulation for broadband wireless applications in very dispersive channels and, in particular, we present some simple and effective equalization algorithms
