В данной работе рассматривается выбор для Республики Ангола системы телерадиовещания ISDB-T. Обобщены результаты экспериментального цифрового телерадиовещания в формате ISDB-T в Республике Ангола. В настоящее время японская система наземного цифрового телерадиовещания (ISDB-T) используется в 14 странах мира, таких как Аргентина, Боливия, Бразилия, Чили, Коста-Рика, Япония, Перу, Парагвай, Сальвадор, Уругвай, Гондурас, Венесуэла, Филиппины, Ботсвана, еще 6 стран, а именно: Ангола, Мальдивы, Шри-Ланка, Гватемала, Эквадор, Никарагуа приняли эту систему. Исследования показывают, что ISDB-T является системой, применимой в нашей стране, так как даже при работе передатчика на 50 % от его максимальной мощности сигнал принимается в большей части города Луанда, причем с ошибками только в регионах, далеких от центра городской застройки. Увеличение мощности ISDB-Т-передатчика, которое предусмотрено, и ряд других изменений может обеспечить уверенный прием программ телерадиовещания в Республике Ангола. Республика Ангола планирует охватить всю национальную территорию страны цифровым телерадиовещанием, начиная с 2023 года.

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.
