Rate Optimization for RIS-Aided mMTC Networks in the Finite Blocklength Regime
Sergi Liesegang, Alessio Zappone, Olga Muñoz +1
Reconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In the context of massive machine-type communications (mM…
Approximations of the Aggregated Interference Statistics for Outage Analysis in Massive MTC
Sergi Liesegang, Antonio Pascual-Iserte, Olga Muñoz
This paper presents several analytic closed-form approximations of the aggregated interference statistics within the framework of uplink massive machine-type communications (mMTC),…
Sensor Selection and Distributed Quantization for Energy Efficiency in Massive MTC
Sergi Liesegang, Olga Muñoz, Antonio Pascual-Iserte
This paper presents an estimation approach within the framework of uplink massive machine-type communications (mMTC) that considers the energy limitations of the devices. We focus…
A Tractable Closed-Form Approximation of the Ergodic Rate in Poisson Cellular Networks
Alexis I. Aravanis, Thanh Tu Lam, Olga Muñoz +2
The employment of stochastic geometry for the analysis and design of ultra dense networks (UDNs) has provided significant insights into network densification. In addition to the ch…
Robust Precoding for Multi-User Visible Light Communications with Quantized Channel Information
Olga Muñoz, Antonio Pascual-Iserte, Guillermo San Arranz
In this paper, we address the design of multi-user multiple-input single-output (MU-MISO) precoders for indoor visible light communication (VLC) systems. The goal is to minimize th…
Effect of Correlated Building Blockages on the Ergodic Capacity of mmWave Systems in Urban Scenarios
Cristian García Ruiz, Olga Muñoz, Antonio Pascual-Iserte
The mmWave bands, considered to support the forthcoming generation of mobile communications technologies, have a well-known vulnerability to blockages. Recent works in the literatu…
Analysis of Blocking in mmWave Cellular Systems: Characterization of the LOS and NLOS Intervals in Urban Scenarios
Cristian García Ruiz, Antonio Pascual-Iserte, Olga Muñoz-Medina
In the millimeter waves (mmWave) bands considered for 5G and beyond, the use of very high frequencies results in the interruption of communication whenever there is no line of sigh…
LOS/NLOS Estimators for mmWave Cellular Systems With Blockages
Tomàs Ortega, Antonio Pascual-Iserte, Olga Muñoz
Designers of millimeter wave (mmWave) cellular systems need to evaluate line-of-sight (LOS) maps to provide good service to users in urban scenarios. In this letter, we derive esti…
