Exploiting faster-than-nyquist signaling
IEEE Transactions on Communications, 2003Faster-than-Nyquist signaling introduces intersymbol interference, but increases the bit rate while preserving the signaling bandwidth. For sinc pulses, it has been established that with a small increase in the signaling rate beyond the Nyquist rate, there is no reduction in the minimum Euclidean distance for binary signaling.

Multistream Faster than Nyquist Signaling [PDF]
IEEE Transactions on Communications, 2009 We extend Mazo's concept of faster-than-Nyquist (FTN) signaling to pulse trains that modulate a bank of subcarriers, a method called two dimensional FTN signaling. The signal processing is similar to orthogonal frequency division multiplex(OFDM) transmission but the subchannels are not orthogonal.

Constrained Capacities for Faster-Than-Nyquist Signaling [PDF]
IEEE Transactions on Information Theory, 2009 This paper deals with capacity computations of faster-than-Nyquist (FTN) signaling. It shows that the capacity of FTN is higher than the orthogonal pulse linear modulation capacity for all pulse shapes except the sinc. FTN signals can in fact achieve the ultimate capacity for the signal power spectral density (PSD).

Generalized faster-than-Nyquist signaling
2012 IEEE International Symposium on Information Theory Proceedings, 2012We extend the concept of faster-than-Nyquist (FTN) signaling to linear digital modulation using arbitrary modulation pulses, called generalized faster-than-Nyquist signaling (GFTN). A universal definition of nominal bandwidth is given so that “how fast” can be measured for GFTN like FTN using T-orthogonal pulses.

{ Asymptotic Optimality of Binary Faster-than-Nyquist Signaling}
IEEE Communications Letters, 2010In this letter, the asymptotic information rate of faster-than-Nyquist (FTN) signaling is examined when the data sequence consists of independent and identically distributed (i.i.d.) binary symbols. It is shown that, as the FTN rate tends to infinity, the information rate converges to that of the FTN signaling with i.i.d. Gaussian symbols.

Capacity of Multicarrier Faster-than-Nyquist Signaling
2020 IEEE International Symposium on Information Theory (ISIT), 2020The channel capacity of multicarrier faster-than- Nyquist signaling is investigated. We develop a suitable discrete- time channel model and derive an explicit and interpretable channel capacity formula for the multicarrier faster-than-Nyquist signaling under frequency-selective channels.

Non Binary and Precoded Faster Than Nyquist Signaling [PDF]
IEEE Transactions on Communications, 2008 Faster than Nyquist (FTN) signaling is an important method of narrowband coding. The concept is extended here to non binary signal constellations; these are much more bandwidth efficient than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is presented.

From the author's abstract: ``The degradation suffered when pulses satisfying the Nyquist criterion are used to transmit binary data in noise at supraconventional rates is studied. Optimum processing of the received waveforms is assumed, and attention is focused on the minimum distance between signal points as a performance criterion. An upper bound on

Polar coding for faster-than-Nyquist signaling
2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017A polar coding scheme for faster than Nyquist (FTN) signaling system, named PcFTN, is proposed in this paper and turbo equalization is adopted to detect the received signal. First, the characteristics of the extrinsic information transfer (EXIT) curve both for polar decoder and FTN detector are analyzed. Then the construction method for polar codes are

Faster than Nyquist signaling with limited computational resources
Physical Communication, 2021Abstract This paper focuses on performance analysis of Faster than Nyquist (FTN) signaling schemes that employ low-density parity-check (LDPC) codes, trellis-based detector and turbo equalization decoding principle. We propose an optimization procedure for shaping pulse design, that takes into account number of trellis states used for equalization ...
