Exploiting spatial diversity in overloaded MIMO LDS-OFDM multiple access systems
(IEEE, 2017)
In this paper, we consider the deployment of multiple antennas as a way to exploit spatial diversity in the uplink of multiple access systems that adopt low-density spreading (LDS) with orthogonal frequency-division ...

Identificación y control de un Vehículo Aéreo no Tripulado tipo Quadcopter
(Editorial bonaventurianaIngenieriasMedellín, 2016)
En este artículo se describe el modelo dinámico de un vehículo aéreo no tripulado tipo QuadCopter, se linealiza alrededor de un punto de operación y se aplica un controlador por realimentación de estados que logra llevar ...
Optimal control of MIMO dead-time linear systems with dead-time compensation structure
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2017-01-01)
State space optimal controllers became popular over the last decades mainly because of its performance and robustness properties, as well as easy extension for multi-variable systems (MIMO). On the other hand, many industrial ...
MIMO millimeter-wave channel estimation using coalitional games
(CEUR-WS, 2018)
In millimeter-wave massive multiple input multiple output (MIMO) antenna systems, channel estimation is a crucial component. In this paper, we propose a virtual channel representation channel estimation method us-ing ...
Neural fuzzy digital filtering: multivariate identifier filters involving multiple inputs and multiple outputs (mimo)
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2011)
Multivariate identifier filters (multiple inputs and multiple outputs - MIMO) are adaptive digital systems having a loop in accordance with an objective function to adjust matrix parameter convergence to observable reference ...

Intelligent reflecting surface assisted secure wireless communications with multiple- transmit and multiple-receive antennas
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
In this paper, we propose intelligent reflecting surfaces (IRS) assisted secure wireless communications with multi-input and multi-output antennas (IRS-MIMOME). The considered scenario is an access point (AP) equipped with ...
Continuous set model predictive control for energy management of modular multilevel matrix converters
(IEEE-INST Electrical Electronics Engineers, 2022)
The modular multilevel matrix converter (M3C) is an
ac to ac power converter composed of 9 arms and is proposed
for high power applications such as motor drive and wind energy
conversion systems. Energy Control of the ...
Secure Beamforming for MIMO Broadcasting With Wireless Information and Power Transfer
(Elsevier, 2015-05)
We consider the Allen–Cahn equation Δu + u(1 − u2) = 0 in R3. We construct
two classes of axially symmetric solutions u = u(|x
|, x3) such that the (multiple)
components of the zero set look for large |x
| like catenoids, ...
