Simulation of a Unmanned Aerial Vehicle (UAV) Swarm Control System
Cursos e Congresos, C-155[Abstract] A promising direction for the use of UAVs is their association into groups or herds,
like the insects observe the principle of swarm organization in the nature. In the case of UAVs,
after combining into a swarm, each drone is controlled by its own automation, and the behavior
of the swarm can be controlled by a program with elements of artificial intelligence or (several)
an operator. In this work, we considered the task of improving the safety of the flight of a group
of UAVs in the agro-industrial complex. The simulation of an unmanned aerial vehicle (UAV)
swarm control system was created by using the 3D simulator Coppeliasim and the software Py-
Charm, and it was implemented when monitoring plants in the agro-industrial comple
Eavesdropping and Jamming via Pilot Attacks in 5G Massive MIMO
Cursos e Congresos, C-155[Abstract] In thiswork, we investigate pilot attacks for 5G single-cell multi-user massive multipleinput
multiple-output (MaMIMO) systems with a single-antenna active eavesdropper and a
single-antenna jammer operating in time-division duplex (TDD) schemes. Firstly, we describe
the attacks when the base station (BS) estimates the channel state information (CSI) based on
the uplink pilot transmissions. Finally, we propose a reinforcement learning (RL)-based framework
for maximizing the system sum rate that proved robust to the eavesdropping and jamming

Numerical Model of a 28-GHz Frequency Diverse Array Antenna
[Abstract] In this work we make use of the frequency diverse array (FDA) concept, whose design is based upon a frequency increment across the antenna elements to generate a beam steering that is a function of angle, time and range. For a possible use of this technique in 5G detection systems, a 28-GHz FDA numerical model, designed with help of a software tool, is analyzed. Some practical conclusions are drawn from the presented results.This research received This work has been funded by the Xunta de Galicia (ED431G2019/01), the Agencia Estatal de Investigación of Spain (TEC2016-75067-C4-1-R, RED2018-102668-T, PID2019-104958RB-C42) and ERDF funds of the EU (FEDER Galicia & AEI/FEDER, UE)Xunta de Galicia; ED431G2019/0
