Information aging in massive MIMO systems affected by phase noise
Alberto Tarable, Francisco J. Escribano
In massive MIMO systems, phase noise can spoil the performance of the usual receiver techniques. The problem arises because of the aging of phase-noise information based on pilots.…
Spectrum-Aware IRS Configuration Techniques for Ultrawideband Signals
Alessandro Nordio, Alberto Tarable, Francisco J. Escribano
Intelligent reflecting surfaces (IRS) have become the subject of many current research efforts, as the ongoing wireless spectrum crunch has made the need to open higher frequency b…
Compensation of Phase Noise in Massive-MIMO Uplink Communications Based on Expectation-Maximization Algorithm
Alberto Tarable, Francisco J. Escribano
Phase noise (PN) is a major disturbance in MIMO systems, where the contribution of different oscillators at the transmitter and the receiver side may degrade the overall performanc…
Reliability Analysis of Slotted Aloha with Capture for an OWC-based IoT system
Milica Petkovic, Tijana Devaja, Dejan Vukobratovic +2
In this article, we consider a random access scheme for an indoor Internet of Things (IoT) framework that uses optical wireless communication (OWC). We focus on a Slotted ALOHA (SA…
Optimization of Chaos-based Coded Modulations for Compensation of Amplifier Nonlinearities
Francisco J. Escribano, José Sáez-Landete, Alexandre Wagemakers
In this work we expand the possibilities of a known class of chaos-based coded modulation (CCM) systems to address the problem of high-power amplifier (HPA) nonlinearity. The hypot…
A Spatial Time-Frequency Hopping Index Modulated Scheme in Turbulence-free Optical Wireless Communication Channels
Francisco J. Escribano, Alexandre Wagemakers, Georges Kaddoum +1
In this article, we propose an index modulation system suitable for optical communications, where the intensity of the light is modulated along the time, space and frequency dimens…
Chaos-Based Multicarrier VLC Modulator With Compensation of LED Nonlinearity
Francisco J. Escribano, José Sáez-Landete, Alexandre Wagemakers
The massive deployment of light-emitting diode (LED) lightning infrastructure has opened the opportunity to reuse it as visible light communication (VLC) to leverage the current RF…
