Análisis de modelos de propagación para televisión digital terrestre (TDT) bajo el estándar ISDB-TB en las ciudades de Ambato y Latacunga del Ecuador.

Abstract

Ecuador adopted ISDB-Td standard for Terrestrial Digital Television; this optimizes the radio spectrum and implements new and interactive audiovisual services. Some TDT signals test emissions are done in Ambato and Latacunga; for the successful TDT implementation, it is necessary to select the propagation model adjusted to the geographic and topographic conditions of the cities. The current research determined the propagation model for the Terrestrial Digital Television under the ISDB-Tb standard that was rather adjusted to the conditions of Ambato and Latacunga due to the similar characteristics of the Andean region, so the results obtained can be extrapolated to the other cities of the region. The research is quantitative since the data taken from the Terrestrial Digital Television channels were analyzed numerically, as well as their length, latitude and power. The propagation model that was better adapted to the geographical conditions of the areas is ITU-R 525/526 and it is recommended to expand the analysis carried out in the current graduation work. In addition, the comparative analysis of the measures taken with the measures simulated was also carried out; this analysis allowed determining that the model was adapted to the requirements.
