The Benefits of Discrete Multi-Tone (DMT) Modulation for VDSL Systems
Overview Multi-Carrier Modulation has features that make it ideal for communications over dispersive channels in which both the insertion loss of the channel and the injected noise are frequency dependent. Practical wireline and wireless channels present such dispersion and frequency dependency, making DMT and OFDM ideal modulations for such environments. This paper discusses DMT's advantages over QAM from the perspectives of performance, flexibility, compatibility, and operational issues, all of which are extremely important to a service provider.
