6G Workshop on Faster-than-Nyquist Signaling

27 July 2020 @ 13:00 - 16:30

Faster-than-Nyquist (FTN) signaling is a promising physical layer technique that has the potential to improve the spectral efficiency (bits/sec/Hz) substantially in communications systems. It refers to the transmission of information-bearing pulses at rates beyond the limit developed in the seminal work of Nyquist back in 1920’s; transmission at FTN rates results in inter-symbol interference (ISI) at the receiver which deteriorates performance (reliability) rapidly. The roots of FTN signaling trace back to 1960s and 1970s; in particular, in was shown in 1975 that one can approach the asymptotic error rate performance of the conventional Nyquist signaling provided that accelerating the pulses does not exceed a certain limit and that complex detection techniques are in place at the receiver to remove ISI (a non-constructive existence theorem). The progress in silicon technology, advances in signal processing techniques, and the emergence of machine learning as a powerful tool in decision making, compounded by the need for ultra-high transmission rates in future networks, make many experts in both academia and industry wonder whether FTN signaling is a technology whose time has finally come.
