Low-Complexity SVD Precoding for Faster-Than-Nyquist Signaling Using High-Order Modulations

IEEE Transactions on Aerospace and Electronic Systems
To address the low spectrum efficiency of satellite communications, faster-than-Nyquist (FTN) signaling has proven a promising technology to improve the spectrum efficiency without requiring additional bandwidth or antennas.

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.

Performance of simplified Faster-than-Nyquist tranceiver

2016 7th International Conference on Information and Communication Systems (ICICS), 2016
As OFDM has become the basis of many of telecommunication standards due to its ease of implementation, stability and efficiency, Faster-than-Nyquist signaling became an interesting base for envisioned telecommunication breakthrough, since it is based on an already used and successfully implemented technology which is OFDM, and it inherently obtains 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 ...

Turbo-coded single-carrier faster-than-Nyquist transmission

2014 IEEE 15th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2014
Faster than Nyquist (FTN) transmission is investigated for a point-to-point AWGN link. The FTN is interpreted as a form of coding at the pulse shape level, and accordingly, the so-called Mazo phenomenon is interpreted as a coding gain. Then, it is shown by simulation that such a gain can disappear in a coded FTN transmission with a powerful FEC code ...

A Robust Timing Recovery Algorithm for Faster-than-Nyquist Digital Multi-band System

Optical Fiber Communications Conference and Exhibition
We propose a novel timing-recovery algorithm (TRA) for faster-than-Nyquist digital-multi-band systems, and experimentally demonstrate that the proposed TRA works for different compression ratios and outperforms conventional TRAs in dispersion and DGD ...

{ Asymptotic Optimality of Binary Faster-than-Nyquist Signaling}

IEEE Communications Letters, 2010
In 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.
