Synchronization for faster than Nyquist signalling transmission
2015 Seventh International Conference on Ubiquitous and Future Networks, 2015In this paper, we investigate the overall receiver architecture when FTN signaling scheme is applied to DVB-S2 standard. In general, the conventional DVB-S2 receiver has not been taken into account for ISI problem seriously except impairment by satellite transponder.

Faster than Nyquist signaling with limited computational resources
Physical Communication, 2021Abstract This paper focuses on performance analysis of Faster than Nyquist (FTN) signaling schemes that employ low-density parity-check (LDPC) codes, trellis-based detector and turbo equalization decoding principle. We propose an optimization procedure for shaping pulse design, that takes into account number of trellis states used for equalization ...

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 ...

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

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.

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.

A Faster-Than-Nyquist (FTN)-Based Multicarrier System
IEEE Transactions on Vehicular Technology, 2019Faster-than-Nyquist (FTN) signaling is regarded as a potential modulation format of 5G communication system for its high spectral efficiency. To further improve the spectral efficiency, researchers have extended the FTN signaling to the frequency dimension.
