Factor Graph Based LMMSE Filtering for Colored Gaussian Processes [PDF]

open access: yes, 2014
We propose a low complexity, graph based linear minimum mean square error (LMMSE) filter in which the non-white characteristics of a random process are taken into account.

Faster-Than-Nyquist Non-Orthogonal Frequency-Division Multiplexing for Visible Light Communications

open access: yesIEEE Access, 2018
In this paper, we propose a faster-than-Nyquist non-orthogonal frequency-division multiplexing (NOFDM) scheme for visible light communications (VLCs) where the multiplexing/demultiplexing employs the inverse fractional cosine transform (IFrCT)/FrCT ...

Discrete Fourier Transform-Based Block Faster-Than- Nyquist Transmission for 5G Wireless Communications

open access: yesApplied Sciences, 2020
Faster-than-Nyquist (FTN) signaling is regarded as a potential candidate for improving data rate and spectral efficiency of 5G new radio (NR). However, complex detectors have to be utilized to eliminate the inter symbol interference (ISI) introduced by ...

A Low-Complexity Graph-Based LMMSE Receiver Designed for Colored Noise Induced by FTN-Signaling

open access: yes, 2014
We propose a low complexity graph-based linear minimum mean square error (LMMSE) equalizer which considers both the intersymbol interference (ISI) and the effect of non-white noise inherent in Faster-than-Nyquist (FTN) signaling.

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 ...

BER performance of finite in time optimal FTN signals for the Viterbi algorithm

open access: yesJournal of Electronic Science and Technology, 2020
In this article, we consider the faster than Nyquist (FTN) technology in aspects of the application of the Viterbi algorithm (VA). Finite in time optimal FTN signals are used to provide a symbol rate higher than the “Nyquist barrier” without any encoding.

A Novel Low Complexity Faster-than-Nyquist (FTN) Signaling Detector for Ultra High-Order QAM

open access: yesIEEE Open Journal of the Communications Society, 2021
Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal pulse modulation technique that can improve the spectral efficiency (SE) of next generation communication systems at the expense of higher detection complexity to remove the introduced ...

Multipath Multiplexing for Capacity Enhancement in SIMO Wireless Systems

open access: yes, 2017
This paper proposes a novel and simple orthogonal faster than Nyquist (OFTN) data transmission and detection approach for a single input multiple output (SIMO) system. It is assumed that the signal having a bandwidth $B$ is transmitted through a wireless

PAPR Reduction of Multicarrier Faster-Than-Nyquist Signals With Partial Transmit Sequence

open access: yesIEEE Access, 2017
Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient transmission scheme for future communication systems. Similar as general multicarrier signals, the high peak-to-average power ratio (PAPR) is also one of the main drawbacks of MFTN

Iterative receiver for faster-than-Nyquist broadcasting

open access: yesElectronics Letters, 2012
Proposed is a faster-than-Nyquist (FTN) broadcast receiver architecture that is based on iterative turbo equalisation. Simulation results for this receiver show that FTN broadcasting can perform close to the capacity boundaries of the Gaussian broadcast channel.
