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.

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 ...

{ Asymptotic Optimality of Binary Faster-than-Nyquist Signaling}
IEEE Communications Letters, 2010In this letter, the asymptotic information rate of faster-than-Nyquist (FTN) signaling is examined when the data sequence consists of independent and identically distributed (i.i.d.) binary symbols. It is shown that, as the FTN rate tends to infinity, the information rate converges to that of the FTN signaling with i.i.d. Gaussian symbols.

Information rates of cyclostationary faster-than-nyquist signaling
2011 12th Canadian Workshop on Information Theory, 2011Faster than Nyquist (FTN) signaling has been studied as an alternative transmission technology in communication systems when information carrying symbols are sent faster than the Nyquist rate determined by the physical channel bandwidth. This paper presents analysis of the information rates of cyclostationary FTN signaling on AWGN and selected 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.

Correlation analysis of the faster-than-nyquist signal
2017 International Conference on Military Technologies (ICMT), 2017The main goal of the paper is to present an analysis of the possibility of using faster-than-nyquist signal processing method to improve performance of navigation system. First the faster-than-nyquist concept is introduced and its pros and cons are described. After that the correlation signal processing in radio-nav systems is explained and one typical

Frequency-Domain Equalization of Faster-than-Nyquist Signaling
IEEE Wireless Communications Letters, 2013In this letter, motivated by the recent rediscovery of faster-than-Nyquist (FTN) signaling transmissions, we conceive a frequency-domain equalization (FDE)-assisted FTN receiver architecture, which is capable of attaining a low demodulating complexity. The proposed scheme is especially beneficial for a long channel tap FTN scenario.
