Receiver Design for Faster-Than-Nyquist Signaling: Deep-Learning-Based Architectures
IEEE Access, 2020 Faster-than-Nyquist (FTN) is a promising paradigm to improve bandwidth utilization at the expense of additional intersymbol interference (ISI). In this paper, we apply state-of-the-art deep learning (DL) technology into receiver design for FTN signaling ...

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

Faster-than-Nyquist Signaling: on Linear and Non-Linear Reduced-Complexity Turbo Equalization [PDF]
, 2017 In the framework of digital video broadcasting by satellite - second generation (DVB-S2), we analyze a faster-than-Nyquist (FTN) system based on turbo equalization and low-density parity-check (LDPC) codes.

Faster-than-Nyquist signaling: value and challenges of 6G-oriented applications
Dianxin kexue, 2021 The faster-than-Nyquist (FTN) signaling technology overlaps multiple streams of data within a symbol period by compressing the transmit symbol time/frequency-domain interval, thus breaking the orthogonality of the Nyquist pulse waveform and achieving the

On the study of faster-than-Nyquist multicarrier signaling based on frame theory [PDF]
, 2014 Multicarrier transmissions are classically based on undercomplete or exact Weyl-Heisenberg Riesz (biorthogonal or orthogonal) bases implemented thanks to oversampled filter-banks. This can be seen as a transmission below the Nyquist rate.

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 ...

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

Iterative-Detection-Aided Tomlinson-Harashima Precoding for Faster-Than-Nyquist Signaling
IEEE Access, 2020 Faster-than-Nyquist(FTN) is a promising technique due to higher spectral efficiency, but at a cost of introducing the inter-symbol interference (ISI) which usually requires the computationally demanding detection algorithms.
