Abstract :
DMT modulation has become a standard communications method for DSL and indoor LAN technology. By utilising the FFT it is able to overcome the problems associated with transmission over a non-flat communications channel. In DSL and indoor LAN technologies, the dominant source of performance impairment is crosstalk. Results are presented here in the context of DMT on an economical cabling scheme which contains a pair of unbalanced transmission lines. The results thus indicate a possible means of performance improvement over current DSL and indoor LAN technologies
