Coexistencia de ISDB-TB de Ecuador y DVB-T2 de Colombia en la ciudad de Tulcán

Abstract

The purpose of this project is to analyze the degree of coexistence of the Digital Terrestrial Television (DTT) systems in the border area between Ecuador and Colombia, because of the DTT standards between them are not the same, ISDB-Tb and DVB -T2 respectively. Prior to the analysis of the coexistence of these digital television technologies or standards, a study is made of their main characteristics, as well as the study of both scenarios, geographical conditions, to choose the appropriate propagation model specifically for these border areas, such as the case of the present project, and be able to implement them virtually. To do this, simulations are used to study the propagation process of digital signals, mainly the coverage that DTT transmitters have with the respective standard, making measurements at the geographic locations given at the border between these countries. The measurements obtained help to estimate an interference threshold and thus be able to propose an optimal propagation model that fits the geographic and climatic conditions in the DTT transmission zones of Ecuador and Colombia, in order to increase the level of coexistence without there are significant interference problems between them.
