On the Detection Algorithm for Faster-than-Nyquist Signaling
2016FTN has been proposed for several decades, and it is attractive for the reason that it can boost the symbol rate without changing the power spectral density. Actually, FTN has been used in some 5G standards. FTN signaling detection is an important element in FTN signaling scheme. In this paper, we shall introduce some FTN signaling detection algorithms

Spectral shaping for faster-than-Nyquist signaling
2014 11th International Symposium on Wireless Communications Systems (ISWCS), 2014Spectral shaping is applied to Faster-Than-Nyquist (FTN) signaling to improve information rates. Under a transmit power constraint, the best shape is an inverse filter but for root raised cosine pulses this requires infinite power at the shaper input. Both input and output power constraints at the shaper are thus proposed as a solution to maximize the ...

Discrete Time Faster-Than-Nyquist Signalling
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Increasing 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 ...

Faster-Than-Nyquist Signaling With Index Modulation
IEEE Wireless Communications Letters, 2017In this letter, we propose a novel faster-than-Nyquist (FTN) transmission scheme relying on the time-domain single-carrier index-modulation (IM) concept. In the proposed FTN with IM (FTN-IM) transmitter, a subset of time-domain FTN symbols are activated, where the combination of the activated symbols conveys additional information further to the ...

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 ...

Faster-than-Nyquist Single-Carrier MIMO Signaling
2016 IEEE Globecom Workshops (GC Wkshps), 2016Faster-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.

Fundamentals of Faster-than-Nyquist Signaling
2016This chapter presents the fundamentals of Faster-than- Nyquist (FTN) signaling. As originally introduced, FTN increases the bit-rate in the signaling bandwidth by packing symbols closer in time, at the cost of introducing intersymbol interference (ISI).

Transmitter architecture for faster-than-Nyquist signaling systems
2009 IEEE International Symposium on Circuits and Systems, 2009This paper presents the complexity analysis of a transmitter architecture for a faster-than-Nyquist (FTN) system. Complexity issues in terms of computations and memory requirements to achieve an FTN system are dealt with. An OFDM based multi-carrier system is considered as it is one of the most widely used in upcoming wireless standards.

Faster-Than-Nyquist Signaling with Constraints on Pulse Shapes
2019 IEEE 30th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2019Faster-Than-Nyquist (FTN) Signaling is a non-orthogonal transmission scheme which violates the Nyquist zero-ISI criterion providing higher throughput and better spectral efficiency than a Nyquist transmission scheme. This comes with a cost of higher transceiver complexity.

On computing the minimum distance for faster than Nyquist signaling
IEEE Transactions on Information Theory, 1990The degradation suffered when pulses satisfying the Nyquist criterion are used to transmit binary data at a rate faster than the Nyquist rate over the ideal band-limited (brick-wall) channel is studied. The minimum distance between received signals is used as a performance criterion. It is well-known that when Nyquist pulses (i.e. pulses satisfying the
