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.

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.

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), 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

An architecture for faster than Nyquist Turbo broadcasting
2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012Recently [16], we have proposed using faster than Nyquist (FTN) signaling to achieve transmission over continuous-time broadcast channels and shown that it can achieve the capacity region of the two-user Gaussian broadcast channel. Benefits of FTN broadcasting include separate encoding and explicit transmission of all users' data, i.e., unlike the ...

Faster than Nyquist, slower than Tropp
2011 4th IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2011The sampling rate of analog-to-digital converters is severely limited by underlying technological constraints. Recently, Tropp et al. proposed a new architecture, called a random demodulator (RD), that attempts to circumvent this limitation by sampling sparse, bandlimited signals at a rate much lower than the Nyquist rate.

Pre-equalized Faster-than-Nyquist Transmission
IEEE Transactions on Communications, 2017Faster-than-Nyquist (FTN) transmission applies non-orthogonal linear modulation to increase spectral efficiency compared with the well-known orthogonal transmission at Nyquist rate. This comes at a price of inter-symbol interference (ISI), which usually is equalized through receiver processing.

Probabilistic Shaping in Faster-Than-Nyquist System
2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2020Probabilistic shaping (PS) in Faster-than-Nyquist (FTN) system is proposed. The proposed system is based on probabilistically shaped 16QAM formats and 8QAM formats. The theoretical average mutual information (AMI) analysis of the proposed FTN PS scheme are analyzed and turns out that the proposed FTN PS scheme is superior to the conventional Nyquist ...
