Generalized faster-than-Nyquist signaling

2012 IEEE International Symposium on Information Theory Proceedings, 2012
We 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), 2020
The 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.

Faster-Than-Nyquist Signaling

Bell System Technical Journal, 1975
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), 2017
A 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

Multi-Carrier Faster-Than-Nyquist Signaling for OTFS Systems

IEEE Transactions on Vehicular Technology
Orthogonal time frequency space (OTFS) modulation technique is promising for high-mobility applications to achieve reliable communications. However, the capacity of OTFS systems is generally limited by the Nyquist criterion, requiring orthogonal pulses ...

Synchronization for faster than Nyquist signalling transmission

2015 Seventh International Conference on Ubiquitous and Future Networks, 2015
In 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 limited computational resources

Physical Communication, 2021
Abstract 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 ...
