Abstract
In this work we seek to approach the choice of the Republic of Angola for the ISDB-T telebroadcasting system. The experimental results of the ISDB-T digital transmission system in the Republic of Angola are Execelente. Currently, the Japanese terrestrial digital broadcasting system (ISDB-T) is used in 14 countries around the world (Argentina, Bolivia, Brazil, Chile, Costa Rica, Japan, Peru, Paraguay, El Salvador, Uruguay, Honduras, Venezuela, Philippines, Botswana) and 6 more countries (Angola, Maldives, Sri Lanka, Guatemala, Ecuador, Nicaragua) have adopted this system. The study shows that ISDB-T is a system applicable in our country, as even with the transmitter operating at 50% of its maximum power, the signal is received in a large part of the city of Luanda, with failures only in regions far from the center urban. The implementation of a fully digital transmitter that is foreseen, the increase of the transmitter's power, among other changes, may provide better advantages in implementing the ISDBT in the Republic of Angola. The commitment comes at a time when Angola plans to cover the entire national territory, starting in 2023.
