Synchronization for faster than Nyquist signalling transmission

2015 Seventh International Conference on Ubiquitous and Future Networks, 2015
In 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 Index Modulation

IEEE Wireless Communications Letters, 2017
In 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 ...

Spectral shaping for faster-than-Nyquist signaling

2014 11th International Symposium on Wireless Communications Systems (ISWCS), 2014
Spectral 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, 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 ...

Faster than Nyquist broadcast signaling

2012 26th Biennial Symposium on Communications (QBSC), 2012
In 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 ...

Signal detection with belief propagation in Faster-than-Nyquist signaling

2017 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2017
Faster-than-Nyquist (FTN) signaling is one of the approaches that improve spectrum efficiency by transmitting symbols faster than the Nyquist rate. However, it suffers from inter-carrier interference (ICI) and inter-block interference (IBI). Thus, the ICI and IBI canceller is needed at a receiver.

On the Detection Algorithm for Faster-than-Nyquist Signaling

2016
FTN 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

On the minimum distance problem for faster-than-Nyquist signaling

IEEE Transactions on Information Theory, 1988
The authors reconsider the problem of determining the minimum distance between output sequences of an ideal band-limiting channel that are generated by uncoded binary sequences transmitted at a rate exceeding the Nyquist rate. For signaling rates up to about 25% faster than the Nyquist rate, it is shown that the minimum distance does not drop below the

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.
