On the minimum distance problem for faster-than-Nyquist signaling
IEEE Transactions on Information Theory, 1988The authors reconsider the problem of determining the minimum distance between output sequences of an ideal band-limiting channel that are generated by uncoded binary sequences transmitted at a rate exceeding the Nyquist rate. For signaling rates up to about 25% faster than the Nyquist rate, it is shown that the minimum distance does not drop below the

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.

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.

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

Synchronization for faster than Nyquist signalling transmission
2015 Seventh International Conference on Ubiquitous and Future Networks, 2015In this paper, we investigate the overall receiver architecture when FTN signaling scheme is applied to DVB-S2 standard. In general, the conventional DVB-S2 receiver has not been taken into account for ISI problem seriously except impairment by satellite transponder.

Faster-Than-Nyquist Signaling With Index Modulation
IEEE Wireless Communications Letters, 2017In this letter, we propose a novel faster-than-Nyquist (FTN) transmission scheme relying on the time-domain single-carrier index-modulation (IM) concept. In the proposed FTN with IM (FTN-IM) transmitter, a subset of time-domain FTN symbols are activated, where the combination of the activated symbols conveys additional information further to the ...

Spectral shaping for faster-than-Nyquist signaling
2014 11th International Symposium on Wireless Communications Systems (ISWCS), 2014Spectral shaping is applied to Faster-Than-Nyquist (FTN) signaling to improve information rates. Under a transmit power constraint, the best shape is an inverse filter but for root raised cosine pulses this requires infinite power at the shaper input. Both input and output power constraints at the shaper are thus proposed as a solution to maximize the ...

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 ...

Discrete Time Faster-Than-Nyquist Signalling
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Increasing the symbol rate up to 25\% faster than the Nyquist criteria for a digital communications system with QPSK modulation with an AWGN channel does not significantly increase the bit error rate or required transmission bandwidth. This so-called Faster-than-Nyquist (FTN) signalling has not been used in commercially deployed communications systems ...
