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

Pre-Equalized Interference Cancellation for Faster-Than-Nyquist Signaling
IEEE Access, 2019 An affine projection (AP)-based equalizer (APE) is introduced to eliminate the inter-symbol interference (ISI) for faster-than-Nyquist (FTN) signaling. Based on the APE, a pre-equalized interference cancellation (PIC) algorithm is proposed to eliminate ...

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 ...

Adaptive Damping Log-Domain Message-Passing Algorithm for FTN-OTFS in V2X Communications [PDF]
SensorsTo enable highly reliable and spectrum-efficient vehicle-to-everything (V2X) communications under conditions with severe Doppler effects and rapidly time-varying channels, we propose a novel faster-than-Nyquist orthogonal time frequency space (FTN-OTFS ...

MIMO Asynchronous MAC with Faster-than-Nyquist (FTN) Signaling
GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023 Faster-than-Nyquist (FTN) signaling is a nonorthogonal transmission technique, which brings in intentional inter-symbol interference. This way it can significantly enhance spectral efficiency for practical pulse shapes such as the root raised cosine pulses.

Superposition Coded Modulation Based Faster‐Than‐Nyquist Signaling [PDF]
Wireless Communications and Mobile Computing, 2018 A structure of faster‐than‐Nyquist (FTN) signaling combined with superposition coded modulation (SCM) is considered. The so‐called FTN‐SCM structure is able to achieve the constrained capacity of FTN signaling and only requires a low detection complexity. By deriving a new observation model suitable for FTN‐SCM, we offer the power allocation based on a

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,
