Pre-Equalized Interference Cancellation for Faster-Than-Nyquist Signaling

open access: yesIEEE 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 ...

MIMO Asynchronous MAC with Faster-than-Nyquist (FTN) Signaling

open access: yesGLOBECOM 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.

On the Capacity of Faster Than Nyquist Signaling [PDF]

open access: yesIEEE Communications Letters, 2020
This letter considers the capacity computations of faster-than-Nyquist (FTN) signaling. It calculates the theoretical capacity of FTN signaling which is obtained by a correlated input. The capacity-achieving power spectral density (PSD) is derived and its superiority over the independent input is shown.

Performance Analysis for Covert Communications Under Faster-Than-Nyquist Signaling [PDF]

open access: yesIEEE Communications Letters, 2022
In this letter, we analyze the performance of covert communications under faster-than-Nyquist (FTN) signaling in the Rayleigh block fading channel. Both Bayesian criterion- and Kullback-Leibler (KL) divergence-based covertness constraints are considered.

Spectral Efficiency Maximization for Deliberate Clipping-Based Multicarrier Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2018
High peak-to-average power ratio (PAPR) is one of the common drawbacks of multicarrier signals at the transmitter. In this paper, we investigate the PAPR reduction of spectral efficient multicarrier faster-than-Nyquist (MFTN) signals, where the PAPR ...
