Resumen en español
Se realizo el estudio del estandar de segunda generación de transmisión de video satelital DVB-S2. Luego, se realizó un análisis de factibilidad de implementación del sistema de transmisión propuesto por dicho estándar y de su posible desempeño en cuanto a tasa de transmisión y ancho de banda. En base a esto, se simplicó dicho sistema a uno con un menor número de subsistemas y conguraciones por cuestiones de alcance del proyecto. Posteriormente, cada uno de los subsistemas del modulador seleccionado fue implementado en VHDL. Se utilizó como criterio de implementación, realizar diseños lo sucientemente exibles para que la adaptación a otras conguraciones sea lo más simple posible. Finalmente, se realizaron simulaciones de comportamiento de cada uno de los subsistemas para validar el correcto funcionamiento de los módulos y, en algunos casos particulares, se contrastaron los resultados obtenidos con modelos computacionales.
Resumen en inglés
The second generation standard of satellite video transmission DVB-S2 was studied. Afterward, a feasibility analysis of the implementation of the transmission system proposed by the standard and its possible performance in terms of transmission rate and bandwidth was carried out. Based on this, the transmission system was simplied to one constituted by a less number of subsystems and congurations because of the limited scope of this project. Subsequently, each of the subsystems of the selected modulator was implemented in VHDL. It was used as an implementation criterion, make designs exible enough to achieve the adaptation to other congurations in the simplest way possible. Finally, behavior simulations of each of the subsystems were carried out to validate the correct functioning of the modules and, in some particular cases, the results were compared with computational models.
