Computer-aided design software for multi-stage amplifiers with bipolar transistors and field effect
(Journal of Physics: Conference Series, 2019-12-19)
The following article presents computer-aided design software for multi-stage amplifiers with bipolar transistors and field effect. It is composed of two units: a design and analysis unit that allows for step-by-step ...
Compensation of frequency mismatch between transmitter and receiver local oscillators to enhance 5G-based radio-over-fiber transmissions
(Journal of Physics: Conference Series, 2020-12-05)
Radio-over-fiber is a cost-effective support for the forthcoming 5G developments aimed to fulfill the ever-increasing demand for information. However, such systems are limited by transmission impairments that reduce the ...
Measurement-based ray-tracing models calibration of the permittivity and conductivity in indoor environmentsCalibración de la permitividad y conductividad en modelos de trazado de rayos basados en medidas
(Ingeniería y Competitividad, 2018-02-11)
In this paper, we show the results of a ray launching tool for channel estimation in indoor scenario and compare it with measurements in a DVB-T system, using a Vector Network Analyzer used to obtain the ...
Algoritmo de nodos adaptativos para solucionar el problema de los nodos huérfanos en una Red Inalámbrica de Sensores ZigBee en topología de árbolAdaptive nodes algorithm to solve the orphan nodes problem in a ZigBee Tree WSN
(Ingeniare, 2021-06)
We have developed an algorithm based on hybrid nodes composed of an XBee S2C module configured
in API mode with escape and connected to a microcontroller ATMEGA 328P to solve the orphan node
problem of a ZigBee tree ...
