Multi-criteria Performance Analysis of Faster Than Nyquist Signaling

, 2018
International audienceIn this paper we propose a multi-criteria comparison of faster than Nyquist (FTN) against Nyquist signaling. To conduct this study we consider uncoded links and maximum likelihood receivers, we fix both the spectral efficiency (SE ...

Scalable Production of Disordered Nickel‐Iron‐Aluminum Oxides as Stable Anodes for Water Electrolysis: The Role of Aluminum

Advanced Materials Interfaces, EarlyView.
Solution precursor plasma spraying enables the scalable fabrication of porous and disordered nickel‐iron‐aluminum oxide coatings as precious‐metal‐free anodes. Aluminum inhibits crystal growth, optimizes local atomic sites, and enhances charge and ion transport to accelerate reaction kinetics, leading to excellent performance and operational stability.

Enhanced Optical Wireless Communications via Deep Neural Network Assisted Pre-Equalization for Faster-than-Nyquist Transmission

Photonics
The Faster-than-Nyquist (FTN) technology is widely used in optical wireless communication (OWC) systems to improve data rates and spectrum efficiency. However, it introduces inter-symbol interference (ISI), which can affect communication reliability.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

A Hybrid Network Integrating MHSA and 1D CNN–Bi-LSTM for Interference Mitigation in Faster-than-Nyquist MIMO Optical Wireless Communications

Photonics
To mitigate inter-symbol interference (ISI) caused by Faster-than-Nyquist (FTN) technology in a multiple input multiple output (MIMO) optical wireless communication (OWC) system, we propose an ISI cancellation algorithm that combines multi-head self ...
