Abstract

A generalization of the well-known DMT/OFDM data transmission method is proposed which can utilize redundancy in the time domain as well as in the frequency domain to completely cancel intersymbol and interchannel interference caused by the channel impulse response. The new systems provide a considerable reduction in latency time and a high increase of bandwidth efficiency and thus open the way to a multiple carrier HDSL similar to the previously introduced ADSL.
