dc.descriptionEn este trabajo se describe el desarrollo de un sistema MIMO-OFDM 2x2 en un ambiente SDR. Se toma en cuenta cada una de las etapas de procesamiento tanto en recepción como en transmisión con los diferentes bloques existentes en GNU Radio; sin embargo, a falta de algunas funciones se ha creado nuevos bloques de procesamiento con la ayuda del lenguaje de programación Python. Se presenta de forma general las características de las tecnologías MIMO, OFDM y MIMO-OFDM. Se describe los diagramas de bloques tanto del sistema de transmisión como de recepción, para una comunicación MIMO-OFDM 2x2. Se presentan las pruebas y los resultados obtenidos en los diferentes entornos. Teniendo así, entornos de simulación con y sin canal de comunicación y entornos de pruebas utilizando los equipos USRP RIO. Finalmente, se presentan las conclusiones.es_ES
dc.description.abstractThis work describes the development of a 2x2 MIMO-OFDM system in an SDR environment. Each of the processing stages is taken into account both in reception and in transmission with the different existing blocks in GNU Radio; however, in the absence of some functions, new processing blocks have been created with the help of the Python programming language. The characteristics of the MIMO, OFDM and MIMO-OFDM technologies are presented in general. The block diagrams of both the transmission and reception system are described for a 2x2 MIMO-OFDM communication. The tests and the results obtained in the different environments are presented. It includes simulation environments with and without communication channel, and test environments using USRP RIO equipment. Finally, the conclusions are presented.l design is performed once the voltage level is selected and, using the DigSilent Power Factory software, the simulations of power flows are carried out for 10 conductors selected for the established period. The results are used to calculate the regulation, efficiency, and power losses of the transmission line. The coordination of insulation is calculated according to the IEC 60815-2008 standard, and for the calculation of the ampacity of the selected conductors, the IEEE-738-1993 standard is used. From the meteorological information of the study area, and with the help of the PEEK formula, it is determined if there is a presence of corona effect. To determine the optimal alternative, it is performed on the investment costs and operating costs of the selected conductors. Finally, by means of the state equations are verified that the selected conductor complies with the mechanical requirements. The mechanical calculations of the transmission line are made with the help of the free software IMEDEXSA 12; and for the budget assement, the referential prices of the EERSSA are used.es_ES
