Abstract
Short radio waves can travel many kilometers by reflection from the ionosphere without using additional communication infrastructure. But modern tasks require high data transfer rates, which requires using a broadband communication channel. In such a communication channel, specific interference occurs, under which a conventional demodulator cannot cope with its task. Therefore, to receive signals, it is necessary to transform the classic demodulator, for example, using machine learning algorithms. A number of such algorithms were analyzed in this article.
