On coding for Faster-Than-Nyquist signaling [PDF]
2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2015 In this paper, we study the design of sparse graph based codes for Faster-Than-Nyquist (FTN) signaling. Using an asymptotic approach based on EXIT charts, we show that good low-density parity check codes can be designed that perform well under iterative detection and decoding and that have better performance than a FTN scheme using a code optimized for

Multistream Faster than Nyquist Signaling [PDF]
IEEE Transactions on Communications, 2009 We extend Mazo's concept of faster-than-Nyquist (FTN) signaling to pulse trains that modulate a bank of subcarriers, a method called two dimensional FTN signaling. The signal processing is similar to orthogonal frequency division multiplex(OFDM) transmission but the subchannels are not orthogonal.

Non Binary and Precoded Faster Than Nyquist Signaling [PDF]
IEEE Transactions on Communications, 2008 Faster than Nyquist (FTN) signaling is an important method of narrowband coding. The concept is extended here to non binary signal constellations; these are much more bandwidth efficient than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is presented.

Time Localization and Capacity of Faster-Than-Nyquist Signaling [PDF]
2015 IEEE Global Communications Conference (GLOBECOM), 2014 In this paper, we consider communication over the bandwidth limited analog white Gaussian noise channel using non-orthogonal pulses. In particular, we consider non-orthogonal transmission by signaling samples at a rate higher than the Nyquist rate. Using the faster-than-Nyquist (FTN) framework, Mazo showed that one may transmit symbols carried by sinc ...

Coordinate Interleaved Faster-Than-Nyquist Signaling
IEEE Communications Letters, 2023 Faster-than-Nyquist (FTN) signaling is an attractive transmission technique which accelerates data symbols beyond the Nyquist rate to improve the spectral efficiency; however, at the expense of higher computational complexity to remove the introduced intersymbol interference (ISI). In this work, we introduce a novel FTN signaling transmission technique,

Multicarrier Faster-Than-Nyquist Based on Efficient Implementation and Probabilistic Shaping
IEEE Access, 2021 The conventional multicarrier faster-than-Nyquist (MFTN) achieves the spectral efficiency (SE) gain by deep compression. However, deep compression leads to severe intersymbol interference (ISI) or intercarrier interference (ICI).
