Abstract: The use of a cyclic prefix in Discrete Multitone(DMT)-|based transmission systems to prevent intersymbol and interchannel interference (ISI/ICI) becomes a significant design|drawback for short-latency systems with short symbol lengths.|We propose a new Generalized DMT (GDMT) scheme which allows to shift the necessary redundancy for ISI/ICI compensation either part-wise or even completely to the frequency|domain. Therewith, we can achieve the shortest possible|latency for a given DFT length. We will show that GDMT offers the same if not better performance at about the same complexity compared to the traditional DMT solution.
