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 ...

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

Performance Analysis for Covert Communications Under Faster-Than-Nyquist Signaling [PDF]
IEEE Communications Letters, 2021 In this letter, we analyze the performance of covert communications under faster-than-Nyquist (FTN) signaling in the Rayleigh block fading channel. Both maximum likelihood criterion- and Kullback-Leibler (KL) divergence-based covertness constraints are ...

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 ...
