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 have shown that GDMT offers the same, if not better, performance at about the same complexity compared to the traditional DMT solution.
