Faster-Than-Nyquist Signal Design for Multiuser Multicell Indoor Visible Light Communications
IEEE Photonics Journal, 2016 We consider a typical indoor environment, where multiple light-emitting diode (LED) lamps are equipped, and each LED lamp is the base station of an optical cell.

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.

IEEE Access, 2017 In this paper, we deal with the intersymbol interference (ISI) cancellation problem induced by the faster-than-Nyquist (FTN) signaling. In the traditional FTN signaling, the detection delay at the receiver depends on the number of states of the ISI ...

Engineering Science and Technology, an International Journal, 2017 The statistical characteristics of non-truncated Intersymbol and Interchannel Interference (ISI/ICI) due to Non-Orthogonal Time-Frequency Signaling (NOTFS) are analytically investigated. The Gaussianity of ISI/ICI is formally discussed in general.

Low-complexity FTN receivers based on frequency domain iterative decision feedback equalization
Tongxin xuebao, 2017 Faster-than-Nyquist (FTN) signaling can improve the system effectiveness without reducing the system reliability,but the fierce inter-symbol interference (ISI) introduced by it may cause that the complexity of the optimal receiver is intolerable.An ...
