Spatially-Coupled Faster-Than-Nyquist Signaling: A Joint Solution to Detection and Code Design
IEEE Transactions on Communications, 2023In this paper, we investigate two important issues of faster-than-Nyquist (FTN) signaling, namely, reduced-complexity detection and code design. Different from previous works, we consider these two issues jointly by designing a scheme that increases the ...

In this article, a joint application of simplified Tomlinson-Harashima precoding (THP) and M-log-maximum a posteriori probability (M-log-MAP) decoder at transceivers is proposed for low complexity faster than Nyquist (FTN) 4-ary pulse amplitude ...

Faster than Nyquist broadcast signaling
2012 26th Biennial Symposium on Communications (QBSC), 2012In this work, we propose using Faster than Nyquist (FTN) signaling to achieve transmission over continuous-time Gaussian broadcast channel. In the FTN broadcasting, different users' messages are completely separated in the coding stage; hence removing the joint encoding that is typically needed in the previously proposed broadcast channel coding ...

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.

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.

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

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.

Multi-Carrier Faster-Than-Nyquist Signaling for OTFS Systems
IEEE Transactions on Vehicular TechnologyOrthogonal 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 ...

Faster-Than-Nyquist Signaling Is Good for Single-Carrier ISAC: An Analytical Study
IEEE Transactions on Signal ProcessingIn this paper, we provide an analytical study of single-carrier faster-than-Nyquist (FTN) signaling for integrated sensing and communications (ISAC). Our derivations show that FTN is advantageous for ISAC, and reveal new insights that these advantages ...
