Discrete Fourier Transform-Based Block Faster-Than- Nyquist Transmission for 5G Wireless Communications

open access: yesApplied Sciences, 2020
Faster-than-Nyquist (FTN) signaling is regarded as a potential candidate for improving data rate and spectral efficiency of 5G new radio (NR). However, complex detectors have to be utilized to eliminate the inter symbol interference (ISI) introduced by ...

Filter Optimization for MFTN-OQAM Systems

open access: yesIEEE Access, 2022
In this paper, a novel and effective method for designing the pulse shaping filter for multicarrier faster-than-Nyquist with offset quadrature amplitude modulation (MFTN-OQAM) systems is proposed.

Multistream Faster than Nyquist Signaling [PDF]

open access: yesIEEE 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.

Coordinate Interleaved Faster-Than-Nyquist Signaling

open access: yesIEEE Communications Letters, 2023
Faster-than-Nyquist (FTN) signaling is an attractive transmission technique which accelerates data symbols beyond the Nyquist rate to improve the spectral efficiency; however, at the expense of higher computational complexity to remove the introduced intersymbol interference (ISI). In this work, we introduce a novel FTN signaling transmission technique,

On coding for Faster-Than-Nyquist signaling [PDF]

open access: yes2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2015
In this paper, we study the design of sparse graph based codes for Faster-Than-Nyquist (FTN) signaling. Using an asymptotic approach based on EXIT charts, we show that good low-density parity check codes can be designed that perform well under iterative detection and decoding and that have better performance than a FTN scheme using a code optimized for

Multicarrier Faster-Than-Nyquist Based on Efficient Implementation and Probabilistic Shaping

open access: yesIEEE Access, 2021
The conventional multicarrier faster-than-Nyquist (MFTN) achieves the spectral efficiency (SE) gain by deep compression. However, deep compression leads to severe intersymbol interference (ISI) or intercarrier interference (ICI).

Constrained Capacities for Faster-Than-Nyquist Signaling [PDF]

open access: yesIEEE 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).
