Expectation-Maximization Learning for Wireless Channel Modeling of Reconfigurable Intelligent Surfaces
José David Vega Sánchez, Luis Urquiza-Aguiar, Martha Cecilia Paredes Paredes +1
Channel modeling is a critical issue when designing or evaluating the performance of reconfigurable intelligent surface (RIS)-assisted communications. Inspired by the promising pot…
Information-Theoretic Security of MIMO Networks under - Shadowed Fading Channels
José David Vega Sánchez, D. P. Moya Osorio, F. Javier López-Martínez +2
This paper investigates the impact of realistic propagation conditions on the achievable secrecy performance of multiple-input multiple-output systems in the presence of an eavesdr…
Survey on Physical Layer Security for 5G Wireless Networks
José David Vega Sánchez, Luis Urquiza-Aguiar, Martha Cecilia Paredes Paredes +1
Physical layer security is a promising approach that can benefit traditional encryption methods. The idea of physical layer security is to take advantage of the features of the pro…
On the Statistics of the Ratio of Non-Constrained Arbitrary α-μ Random Variables: a General Framework and Applications
J. D. Vega Sánchez, D. P. Moya Osorio, E. E. Benitez Olivo +3
In this paper, we derive closed-form exact expressions for the main statistics of the ratio of squared alpha-mu random variables, which are of interest in many scenarios for future…
The Problem of Peak-to-Average Power Ratio in OFDM Systems
Martha C. Paredes Paredes, M. Julia Fernández-Getino García
Orthogonal Frequency Division Multiplexing (OFDM) is widely used in many digital communication systems due to its advantages such us high bit rate, strong immunity to multipath and…
