Discrete Time Faster-Than-Nyquist Signalling

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
Increasing 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 ...

Analysis and Design of Improved 5G LDPC Codes for Faster-Than-Nyquist Signaling

International Symposium on Information Theory
This paper focuses on the analysis and design of improved 5G low-density parity-check (LDPC) codes for faster-than-Nyquist (FTN) signaling. We first propose the protograph-based extrinsic information transfer (PEXIT) chart analysis for the LDPC-coded FTN

Interference Mitigation for Faster-Than-Nyquist $m$CAP in Bandlimited VLC: A Low-Complexity Gapped Index Modulation Approach

Journal of Lightwave Technology
In  this paper, a novel gapped index modulation (GIM) scheme is proposed and investigated to mitigate the inter-band interference (IBI) with low complexity in faster-than-Nyquist multi-band carrierless amplitude and phase modulation (FTN-$m$CAP) based ...

Faster-than-Nyquist Single-Carrier MIMO Signaling

2016 IEEE Globecom Workshops (GC Wkshps), 2016
Faster-Than-Nyquist (FTN) signaling is created when a digital communications signal has an occupied bandwidth less than the symbol rate. It has been previously demonstrated that FTN signals can achieve bit error rates near that of full-bandwidth signaling for BPSK and 4-QPSK modulation.

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.

A New EP-Based Sequential Kalman Smoother: An Application to Faster-Than-Nyquist Signaling

ICC 2025 - IEEE International Conference on Communications
This paper presents a novel turbo-equalizer based on Backward Information Forward Marginals (BIFM) Kalman smoothing. We extend this Kalman smoother with an Expectation Propagation (EP) based message passing strategy to derive an iterative time-domain ...

Probabilistic Shaping in Faster-Than-Nyquist System

2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2020
Probabilistic 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 ...
